Board measurement table in cubes. How many square meters of board in a cube: dimensions of products, number of parts, calculation of volume and area
Construction work requires the solution of many different issues, among which the most important task is the selection and purchase of lumber. It is not difficult to calculate how many linear meters of boards and beams will be needed during the construction process. But the price of industrial wood is indicated for 1 cubic meter, and this often causes difficulties for novice home craftsmen. The ability to correctly select and calculate the amount of edged or unedged lumber in a cube will save money and avoid a situation when, after the completion of construction work, a pile of unused boards remains on the site.
Classification and characteristics of sawn timber
The very name "sawn timber" suggests that this type of building material is obtained by longitudinal sawing of tree trunks on circular or band saws. For the production of boards and beams, several sawing methods are used:
- tangential (in a circle),
- radial.
Tangential sawing means the saw to travel tangentially to the tree rings, which reduces waste and therefore reduces the cost of building materials. The boards obtained in this way have a beautiful, pronounced pattern, therefore they are often used for finishing purposes. Disadvantages of circular sawing include the tendency of wood to shrink and swell, as well as a significant difference in texture as the cutting tool approaches the center of the log.
There are several ways to cut the trunk in the sawmill.
With a radial cut, the cutting line goes through the core of the tree, so the output of the boards will be less and their price will be higher. Nevertheless, if it is necessary to obtain high quality wood, this method is used. This is due to the fact that, in comparison with the tangential method, radial sawing boards have two times reduced swelling and shrinkage rates. In addition to the sawing methods discussed above, a mixed method is also used, which combines the advantages of the first two.
The concept of lumber actually includes more than the traditional moldings that are most often seen in the construction markets. A complete list of products that are obtained when sawing logs includes:
- board;
- timber;
- bar;
- lagging;
- croaker.
The last two types of sawn timber are waste, which absolutely does not prevent them from being used for certain types of construction work, as well as for finishing purposes.
Planks
Planks include rectangular sawn timber with a thickness of no more than 100 mm and a ratio of width to thickness of at least 2: 1. Depending on the degree of processing, the board can be edged or unedged. The first is a finished product without bark and with smoothly sawn edges, while the second is a “semi-finished product” taken directly from the saw frame.
The edged board has straight edges and a constant width along the entire length of the lumber
The most commonly used boards in construction are of the following standard sizes:
- thickness - 25 mm, 40 mm, 50 mm, 60 mm;
- width - from 75 to 275 mm with gradation every 25 mm;
- length - from 1 m to 6.5 mm with a step of 250 mm.
Boards of other sizes can be obtained by cutting or planing standard sawn timber, as well as by making an individual order for sawing round timber.
Unedged board has a lower cost, however, without finishing, the scope of its application is limited.
The parameters of lumber used in construction are standardized and determined according to the current GOST 8486–86 for softwood and GOST 2695–83 for hardwood.
Beams
A bar is called lumber, the cross-section of which is a square with sides of at least 100 mm. The size of the bar in cross-section is unified and can vary from 100 to 250 mm with a step of 25 mm. The standard determines the length of products of this type from 2 to 9 m, but most often square-section lumber is used with a length of no more than 6 m.In some cases, products with a cross-section of 150x100 mm, 200x100 mm or 200x150 mm, which according to the existing classification are much closer, are mistakenly referred to as timber. to the sleepers.
The timber is an ideal material for the construction of frames and other wooden structures.
The bar differs from the bar discussed above only in that its section does not exceed 100x100 mm. The typical bar length is also 6 m, and the cross-sectional size ranges from 40 mm to 90 mm in 10 mm increments. To simplify the classification, bars are often referred to as a rail, in which the section has a rectangular shape, and the ratio of thickness to width is at least 1: 2. The standard row of edges of softwood laths looks like this: 16, 19, 22, 25, 32, 40, 44, 50, 60, 75 mm. For hardwood lumber, products of increased width are additionally provided, and the product line itself looks like this: 19, 22, 25, 32, 40, 45, 50, 60, 70, 80, 90, 100 mm.
A variety of bars and slats allow you to strengthen and make any wooden structure as stable as possible
Obapol and croaker
Obapol is the very first cut of round timber, in which the outer surface remains untreated. Unlike obapol, the slab can have a cut in half of the second side or an alternation of treated and untreated areas on the bark side. The importance of obapol and slab in construction is secondary, since the unaesthetic appearance and reduced operational characteristics make it possible to use lumber of this type only for auxiliary purposes. Most often, slab and obapol are used as a fastening material, as well as for the manufacture of formwork, lathing or flooring of scaffolding. This material is also interesting as a decorative material for decorating walls, fences and other vertical structures.
Despite the external ugliness, slab and obapol are widely used for secondary construction tasks.
Technology for calculating the number of boards in a cube
On the timber market there are both edged sawn timber and unedged board, along the edges of which there is wane. Depending on the type of wood products, several methods are used to determine the cubic capacity.
How to find out the amount of edged lumber in a cube
The algorithm for determining the cubic capacity of lumber is based on the formula known to every schoolchild for finding the volume of a rectangular parallelepiped. In order to find out the cubic capacity of one board (V) in cube. m, you need to find the product of its length (a) by width (b) and thickness (h) in meters V = a × b × h.
The desired figure will make it easy to calculate how many boards of this type will fit in one cubic meter of lumber. For this, 1 cubic meter. m of lumber is divided by the volume of one product. For example, if you need to find out the cubic capacity of one board with parameters 6000x200x25 mm, then substituting these numbers into the formula, we get V = 6x0.2x0.025 = 0.03 cubic meters. m. Consequently, in one cubic meter there will be 1 / 0.03 = 33.3 such products.
The tongue-and-groove board has a groove on one side and a tongue on the other. Since both of these elements are approximately equal to each other, their parameters can be neglected. That is why the size of grooved lumber in diameter is measured without taking into account the locking part.
In the case of boards that have the same dimensions, the calculation can be simplified by substituting the dimensions of the lumber pile in the formula. Of course, at the same time, its laying should be as dense as possible, otherwise the gaps between the individual elements will affect the accuracy of the calculations. Considering that the cost of certain types of wood reaches tens of thousands of rubles, such an error can result in a round pretty penny.
To simplify calculations, you can use special tables that allow you to quickly determine the volume or amount of wood in 1 cubic meter. m of lumber.
Table: the number of edged boards in 1 cubic meter m of lumber of standard length
| Board size, mm | The number of boards with a length of 6 m in 1 cubic meter m | The volume of one board, cubic meters m |
| 25x100 | 66,6 | 0.015 |
| 25x150 | 44,4 | 0.022 |
| 25x200 | 33,3 | 0.03 |
| 40x100 | 62,5 | 0.024 |
| 40x150 | 41,6 | 0.036 |
| 40x200 | 31,2 | 0.048 |
| 50x100 | 33,3 | 0.03 |
| 50x150 | 22,2 | 0.045 |
| 50x200 | 16,6 | 0.06 |
| 50x250 | 13,3 | 0.075 |
The cubic capacity of a bar of standard sizes can also be determined using the table below.
Table: the amount of timber in 1 cubic meter m of lumber
| Bar size, mm | The number of products with a length of 6 m in 1 cubic meter m | Volume of 1 bar, cubic meters m |
| 100x100 | 16.6 | 0.06 |
| 100x150 | 11.1 | 0.09 |
| 100x200 | 8.3 | 0.12 |
| 150x150 | 7.4 | 0.135 |
| 150x200 | 5.5 | 0.18 |
| 150x300 | 3.7 | 0.27 |
| 200x200 | 4.1 | 0.24 |
Very often it is required to determine the surface area (floor or wall) that can be covered with a board of one thickness or another with a volume of 1 cubic meter. m. To do this, you can use the formula S = 1 / h, where h is the thickness of the lumber. So, one cubic meter of a 40 mm board will be enough to equip S = 1 / 0.04 = 25 square meters. m of floor. To facilitate the process of calculating the area, a table called a cubature allows. It contains data on the section of the boards, their number in 1 cubic meter. m and the required area that they can cover.
Method for calculating the cubic capacity of an unedged board
Unedged lumber is not pruned at the edges, therefore, not only the size across the individual products differs, but also the width of different parts of the same board. In this regard, it is possible to calculate the volume of a pile of untreated sawn timber only approximately. The same applies to the calculation of the cubic capacity of a separate unedged lumber, although the error in this case will be much smaller.
So, to calculate the cubic capacity of an unedged board, there are two constant values - thickness and length, and one variable - width. To avoid complex calculations using differential algebra methods, the last parameter is simply averaged. To do this, the board is measured in several places and the arithmetic mean is found. For example, for a board with a diameter of 400 mm at the base, 350 mm wide in the middle and 280 at the top, the calculated value will be (430 + 340 + 260) / 3 = 343 mm. Further calculations are carried out in the same way as for edged sawn timber.
Most often, the width of the unedged board is determined only on the basis of measurements along the edges of the lumber. It should be noted that the accuracy of calculations directly depends on the number of measurements, therefore, in critical cases, their number is increased.
If you want to know the cubic capacity of a package of unedged wood, then the products are stacked on top of each other in such a way that the following conditions are met:
- stacks must be aligned along the front end;
- boards in a stack should not overlap;
- it is not allowed to change the width of the package along the entire length of the lumber;
- the protrusion of the end products outside the stack should not exceed 100 mm.
Having measured the height, length and width of a package of unedged timber with a tape measure, the approximate cubic capacity is determined using the formula V = a × b × h. To find out a more accurate value, the result is multiplied by the stacking factor, which can be found out from special tables.
The construction of a private house, summer house or any other building requires an estimate. It indicates the amount of building materials and their cost. There are several methods for performing the corresponding calculations. Plank is a common material that is used everywhere. In order to determine how many boards are in a cube, you need to familiarize yourself with the calculation options and the nuances of this process.
The calculation of the cubic capacity of the board will depend on the degree of processing of the material, type and grade
How many boards are in a cube: types of lumber and features of their calculation
The boards used in the construction of houses and other structures differ in several ways. First of all, the material from which they are made is taken into account. The technical characteristics of the product depend on the type of wood. Depending on the method of production, these building elements are divided into types:
- edged;
Almost all wood products: edged lumber, planed, structural, etc. measured in cubes (cubic meters)
- unedged.
The first of them belong to the highest grade and have the correct shape, since all of their faces are amenable to processing. In turn, unedged products are most often used to organize rough flooring, etc. The peculiarity of this material is that its lateral edges are not processed, they contain bark and have a natural shape. This simplifies the production of unedged boards and affects its cost.
In order to answer the question of how to calculate the cube of the board, you must first decide which of the materials will be used in the construction process. For example, it is easier to calculate the cubic capacity and cost of a cut part, since it has a geometrically correct shape.
For unedged products, there are constant values that are arithmetic mean numbers. The table of boards in a cube in this case is not always suitable, since it takes into account the rounding of even edged sawn timber.
To purchase lining, you may need to make calculations to find out what area of material is available in a cubic meter.
Separately, it should be said about building materials for finishing. This group includes floorboards, lining, block house and products that imitate timber. The design of these finished parts includes special ribs and grooves necessary for the tight connection of individual elements to each other.
Helpful information! When calculating the finishing lumber, you need to focus only on the dimensions of the main part of the board. Thus, the size of the tool joints is not taken into account; only the numerical values of the product body are taken for the calculation.
Regardless of what type of material is used, a single formula is used to calculate the number of boards in a cube. An exception in this case is unedged products. Their calculation has its own characteristics, because such parts do not have all the faces necessary for the calculation.
Cube volume formula: how many edged boards in 1 cubic meter
A cube is a geometric figure that consists of 6 equivalent faces. Each of them is a square. To determine the volume of this figure, it is necessary to multiply 3 indicators among themselves:
- length;
To determine the number of trimmed boards in 1 cube, you need to find out the volume of one of them by finding the product of three quantities, and then divide 1m3 by it
- width;
- height.
In order to find out how many boards are in 1 cube, you need to multiply several values. The result is a mathematical expression that looks like this:
V = h x b x L, where:
h is the height of the cut product (m);
b - element width (m);
L - length of one part (m).
Using this formula, you can determine the volume of 1 element. It is important to remember that when carrying out the calculation, it is necessary to convert the millimeter values of the product into meters. For example, in order to determine how many 25x150x6000 boards are in a cube, you will need to convert the numbers by multiplying them by 0.001. The finished mathematical expression after such a transformation will look like this:
V = 0.025 x 0.15 x 6
The calculation algorithm is the same for all sawn timber of a certain group, regardless of their features.
The result is that the volume of one piece of wood is 0.0225 cubic meters (m³). Next, it remains to calculate how many pieces of edged boards are contained in 1 cubic meter. There is a simple formula for this. It means dividing 1 cubic meter by the volume of 1 board, which was obtained using the previous mathematical expression. Let's consider the calculation using an example:
1 m³ / 0.0225 m³ = 44.4
Thus, 1 cubic meter contains approximately (if rounded off) 44 boards. After that, it is already possible to independently determine the amount of material required for the construction of a specific structure. And also at this stage, you can draw up a general estimate indicating the price of edged boards per cubic meter.
To calculate the cost of 1 edged board, a mathematical expression is used, which implies multiplying the volume of 1 part by the price of a cubic meter. Let's take an example:
0.0225 x 8200 rubles. = RUB 184.5
The calculation showed that the cost of 1 edged product will be approximately 184 rubles. If the cost of 1 part is known, but it is necessary to calculate the price of a cube of a board, you need to do the reverse manipulation. In this situation, you will need to divide the price for 1 item (184.5) by its volume (0.0225).
After some calculations, you can find out that 1 cubic meter contains approximately 44 boards
Note! Sometimes, especially when buying a small batch of boards, there is a confusion with the decimal places. In some cases, sellers of sawn timber deliberately quote the cost, calculated when rounded to 3 numbers. However, by law, this value is only suitable for large batches of boards. When purchasing several products, it is recommended to round in accordance with GOST, namely, to 0.000001 m³.
When calculating the amount of boards and the cost of lumber per cubic meter, it is advisable to take into account unplanned losses, which very often occur during construction. Therefore, it is recommended to buy edged products with a small stock (several pieces).
How many boards in a cube: calculation of unedged lumber
The calculation of the cubic capacity of an unedged board has some nuances, since its shape is not correct. Such material does not have a rectangular section along its entire length, therefore it is used to organize temporary structures. The lower and upper surfaces of the unedged board must be processed along the entire length. Otherwise, this product is a side part of the log (slab).
The calculation of the cubic capacity will depend on the degree of processing of the material, type and grade, for example, edged and unedged boards are calculated differently
There are several methods to find the volume of unedged lumber in 1 cubic meter, as well as its quantity. It should be noted right away that it is rather difficult to determine how many boards are in one cube when it comes to irregular geometric shapes. Therefore, the initial numbers obtained when calculating unedged parts will be an approximate figure.
Consider what methods are used to calculate the cubic capacity and the amount of unedged sawn timber:
- batch;
- piece by piece;
- sampling method.
In the first case, you will need to load the lumber into a bag that must have the correct shape. After the bookmark, you need to measure the desired indicators. The following is a standard procedure for determining the volume using the measured values. This method is most common for products that do not have clear edges. For example, using it you can calculate the cubes of a 25x150x6000 board in a cube (unedged).
For the width of the unedged board, when calculating, take the average indicator
It is worth noting that this type of mathematical expression uses a special coefficient (for the width), which is the arithmetic mean. Although this option is not fast, it allows you to answer the question of how to calculate the cube of the board.
The piece-by-piece method involves the use of numbers corresponding to the arithmetic mean of the height and width of the trimmed product. These values are calculated in meters.
In order to find the arithmetic mean, it is necessary to measure the board. The minimum width (at the narrowest point) and the maximum are measured. Further, both indicators are added up and divided in half. After that, the same height manipulation is performed. The numbers obtained during the calculation must be multiplied by each other and by the length of the product.
Let's see how this looks like a mathematical expression:
(b max + b min) / 2 x (h max + h min) / 2 x L = V
When calculating large consignments of wooden building materials by the method of determining the volume, the sampling method is taken
Using such a formula, it will not be difficult to determine the volume of 1 unedged element and answer the question of how to calculate the cubic capacity of a part. After obtaining this value, you can calculate the total number of boards in a cubic meter. For such a calculation, you will need to use a formula similar to the cut part (a cubic meter is divided by the volume of the product).
Helpful information! When buying raw boards, you need to be careful. Sellers should use a factor that affects the reduction in total volume, taking into account future shrinkage. To calculate wet coniferous products, 1 cubic meter must be multiplied by 0.96. In turn, the coefficient for hardwood is 0.95.
The last way to determine the volume of lumber and its quantity in 1 cubic meter is the sampling method. It is used when calculating large quantities of wooden building materials. The essence of this method is that several boards are selected from the total mass. Then the parts are measured and calculated in accordance with the piece-by-piece method. The resulting numbers are multiplied by the total number of parts in the batch.
An unedged board has a large spread in width at opposite ends, therefore, when calculating an unedged board, the average width must be substituted into the formula
How many boards in a cube 50x150x6000 in a cube: payment
As an example, you can take an unedged product with dimensions of 50 by 150 by 6000 mm. First, we convert millimeters to meters. Some people don't know how many millimeters are in 1 meter. To convert, you need to multiply the required number in mm by a factor of 0.001. In its finished form (with substituted values), the formula will look like this:
(0.155 + 0.145) / 2 x (0.055 + 0.045) / 2 x 6 = V
After adding and dividing by 2, we get the arithmetic average of the width and height of the unedged part. Thus, the formula takes on a more understandable, standard form:
0.15 x 0.05 x 6 = 0.045
This is how the calculation is made, the result of which is finding the volume of 1 board. To determine the number of products in 1 cubic meter, the same formula is used as in the case of an edged analogue.
Before determining how many boards 50x150x6000mm fit in 1 cubic meter, you need to convert millimeters to meters
If necessary, you can calculate the area of one board. Most often this is required when the manufacturer indicates the price per square meter, and not per cubic meter. The area formula involves multiplying the width of a part by its length. It is important in this case not to be mistaken and not to forget to convert millimeters to meters.
In order to determine the cost, the same formula is used as in the case of edged lumber. You just need to multiply the volume of 1 part by the amount that corresponds to the total price of the cube. This is how the cubes are calculated in the cube of a 50x150x6000 board.
Calculating a board using an online calculator
Perhaps the easiest way (along with the lumber cubic table) to determine the exact value of the volume and number of wooden planks is an online calculator. It is a program with predetermined algorithms that allow you to calculate all the required values of lumber. This method makes it possible to calculate not only the edged board, but also other varieties of these products.
Note! In order to avoid the likelihood of an error when calculating the material on the online calculator, you should immediately indicate for which board the measurement is used.
In order not to be mistaken when calculating the material on the online calculator, you need to indicate for which board the measurement is used
The process itself is quite simple. First, you need to find a calculator on one of the specialized sites using the search line of your browser. Next, you need to enter the necessary indicators in the appropriate cells. The cube board calculator will calculate on its own.
This method is popular and allows you to quickly and accurately determine all the necessary values \ u200b \ u200bof the lumber. When using the calculator, it is recommended to check the filling accuracy several times. In the event of an error, the calculation will be performed incorrectly, which is fraught with serious discrepancies in the final figures.
How many boards in a cube: table (6 meters)and tips for its use
The last method to determine the quantity and volume of wood products is to use a special table. This method is very convenient as it does not require lengthy calculations. All that is needed is simply to find the desired value in the table using the original data (width, height and length).
In order to quickly find the correct answer to the question of how many boards are in one cube, the table is best suited. However, experts point out one drawback of this method: numbers corresponding to cubic capacity or quantity are often rounded. Therefore, if you need to perform the most accurate calculation, it is recommended to carry out all the calculations yourself.
The volume of edged boards in a cube:
| Board dimensions, mm | Length, m | Volume of 1 piece, m³ |
| 50 to 200 | 6 | 0,06 |
| 30 to 100 | 0,018 | |
| 20 to 150 | 0,018 | |
| 30 to 150 | 0,027 | |
| 20 to 200 | 0,024 | |
| 30 to 200 | 0,036 | |
| 25 to 100 | 0,015 | |
| 40 to 100 | 0,024 | |
| 25 to 150 | 0,0225 | |
| 40 to 150 | 0,036 | |
| 25 to 200 | 0,03 | |
| 50 to 100 | 0,03 | |
| 40 to 200 | 0,048 | |
| 50 to 150 | 0,045 | |
| 20 to 100 | 0,012 |
In addition, before starting the search for the desired value, it is advisable to make sure that the length of the lumber is consistent. The tables can be different, containing information about the cubic capacity of boards with a length of 3, 4 or 6 m. Today, the most common products are wooden products, the length of which is 6 meters. How many boards are in one cube? The table to determine the amount of lumber also uses rounded values.
Using the tables, you can determine the approximate number of boards in a cube without resorting to calculations
Do not forget that the board can be made from different types of wood. Therefore, before starting to use the table, it is recommended to make sure that you have selected the type of lumber you need.
How many boards are in 1 cube: table (6 meters):
| Board dimensions, mm | Length, m | Number of pieces in 1 m³ |
The tabular method is good in that it does not require calculations or self-filling in the overall and other values of the lumber to get an answer. It is suitable for determining the cubic capacity, and also allows you to answer the question of how many boards are in a cube. The table is ideal for calculating large quantities of a product.
Prices of edged boards per cube: 50x150x6000and other varieties
Today in the construction market you can find many types of lumber. All of them are differentiated not only by size, but also by the type of wood from which they were made. And also the cost of these products is influenced by the production technology and their purpose. In order to find out how much a cube of a board costs, you need to familiarize yourself with all the varieties of these parts.
1st grade sawn timber, made in accordance with technical specifications, costs an average of about 7,000 rubles. per cube
The most popular in the construction of private houses, summer cottages, as well as other structures is the classic edged board. It can be of 1st and 2nd grade. The first option is more expensive, as it has higher technical characteristics and durability.
Helpful information! The price for an edged board of the 1st grade is approximately 7,500 rubles. for 1 cubic meter Products that belong to a lower quality group cost about 4-6 thousand rubles. for 1 m³.
The width and height of the boards, as a rule, do not affect their cost. This is due to the fact that in a cubic meter, regardless of the dimensions of the timber, there will be the same number of parts. In the sense that for the same price you will receive 44 edged boards 25x1500x6000 (price per cube: 7500 rubles) or 22 parts 50x150 having the same length.
Separately, it should be said about edged boards made in accordance with the technical specifications (TU). Lumber of this type costs on average about 7,000 rubles. per cubic meter Such boards have good quality characteristics and can be used in the construction of various structures.
Building board is often used in interior decoration
Unedged products are cheaper because they are of lower quality. Their cost is calculated using averaged values. The price of unedged sawn timber ranges from 4 to 5 thousand rubles. However, they are not recommended for construction. It is better to use better quality lumber, for example, edged boards 40x150x6000 (price per cube: 7500) or similar products with other dimensions.
When buying timber, you need to pay attention to some points. For example, the board must be flat. The curvature of the product most often indicates that the technology was violated during its production. Such parts are not used in construction, as they do not have the required quality.
How much does the cube of the board weigh? When purchasing this building material, you should take into account its mass. For example, an edged board made from dry spruce weighs 450 kg (1 cubic meter). 1 m³ of raw product has a mass of 790 kg. Dry pine has a weight of 470, and wet - 890 kg. This knowledge will be needed when transporting products.
When choosing a board, it is necessary to check if there are knots on it, since their presence greatly disrupts the internal structure and leads to a decrease in strength characteristics
When choosing lumber and calculating it, you need to be careful. The board should not have cracks, chips or other defects. Small cracks are allowed, but it is recommended to buy a solid, high-quality product that meets GOST. And also you should pay attention to the presence of knots. This is due to the fact that they negatively affect the strength of the wooden part. The choice of the calculation method depends on the specific case. If necessary, you can always use the services of specialists who will help you perform the correct calculation and make an estimate.

Video: How many boards per cubic meter. Memo to the developer
Beams and boards are one of the oldest building materials, but they do not lose their relevance today. At the same time, the cost of these sawn timber makes buyers pay close attention to the accuracy of calculating their required amount.
Now you can find on the worldwide network the necessary tables for calculating the required number of cubic meters of building materials, but a skilled owner must be able to calculate on his own.
How many boards in a cube are 50 x 150 x 6000
As you probably already understood, the calculation of lumber is carried out in cubic meters. At the same time, a cube of boards and beams may have different dimensions. Therefore, for an accurate purchase, you need to understand the size of this cube for a more accurate calculation. The most common cube of lumber has dimensions of 50x150x6000 mm.
We calculate the required volume easily and simply
It is very easy to calculate the cubic meters of a board or timber. To do this, you need to have basic knowledge of geometry, which we were told at school. Thus, to determine the required cubic capacity, you need to initially multiply the indicators of width (l), thickness (s) and length (b).
For example: s boards × l boards x b boards = 50 mm × 150 mm x 6000 mm = 45000 cm / cube.
We remember that a cubic meter is equal to 1,000,000 cubic centimeters, that is, 100 cm x 100 cm x 100 cm.
1,000,000 cc / cm: 45,000 cc / cm = 22.22 pieces boards in one cube.

How to calculate how much timber is in 1 cube?
We offer a simple calculation so that you do not get lost with the question of how to find out how much timber is in a cube. These calculation options are suitable if you know the dimensions of the timber. For example, let's take a beam 260 x 260 x 6,000 mm (6 meters). The same can be done for a bar measuring 3 meters, 4 meters, 5 meters.
The formula for calculating the volume of a bar:
100mm 100mm 6000 mm = 0.1m 0.1m 6m = 0.06 m 3
The formula for calculating the timber in pieces:
Timber length - 6 meters
1m 3 / 0.06m 3 = 16 pcs / m 3
Hard? It seems to be not! But if the calculation causes you difficulties, just use our table. The table contains a calculation for all known bar sizes, which are given in GOST 8486-86.
The page contains answers to simple questions from people:
- How many timber
- How many cubes of timber
- How many pieces of timber cube
- How much timber is needed
- How many in one cube
- How many pieces in a cube
- How many bars in a cube
- How to calculate how much timber is in 1 cube
Why know how much timber is in 1 cube?
There are two reasons for this:
- You can immediately calculate the total price of the volume of timber you need. To do this, you need to know the volume of 1 piece of timber, the price for 1 cubic meter and how many pieces will be needed to implement your plans.
- You can calculate the total number of timber units needed to complete the project. And this can be done, knowing how many cubes are required for work, and calculating the number of pieces of timber in 1 cube.
There is no construction site that would have done without the use of sawn timber.
Therefore, it becomes necessary to determine their exact number. You can calculate how many boards are in 1 cube using formulas, or you can use ready-made tables. These tables are called cubes.
Note that coniferous wood products are considered here.
What is cubic capacity
In general, this is the volume of a body, expressed in cubic measures.
Cubic capacity of lumber is the volume of lumber, expressed in cubic meters, otherwise - in cubic meters or simply in cubes.
Types of lumber
In this section, we will tell you about lumber in the order in which they are obtained when cutting a log.
Obapol and croaker
For some reason, confusion arises with the definition of these materials: someone claims that they are one and the same, and someone claims that obapol is produced from a slab.
The proposed table will provide complete clarity.
As you can see from the table, obapol is not used in construction, so we will not consider it in the future.
The requirements for the slab are standardized in accordance with OST 13-28-74. This means that the croaker is a full-fledged building material.
Croaker is used:
- for the device of the subfloor;
- roof battens;
- manufacture of formwork.
Unedged board
It is cut along two opposite surfaces called faces. The edges remain uncut, hence the name.
Its standard sizes are as follows: thickness - 25, 40 and 50 mm; length - 6 m.
The scope is wider than that of a slab.
It is also used for construction:
- warehouses;
- utility rooms;
- temporary fences;
- awnings.
In addition, it can serve as a base for clapboard cladding, block house and other finishing materials.
Edged board
It differs from unedged one in that it is cut along the faces and edges.
It is used as:
- roof battens;
- lathing of the walls of frame houses;
- racks and braces of frame houses;
- stairs;
- material for the manufacture of country furniture, etc.
Beams
This is sawn timber with a thickness of 100 mm or more with a difference in width and height of the section no more than two times. Usually the timber is square. The most used timber has a cross section of 100 × 100 mm and 150 × 150 mm.
Used by:
- in the construction of frame houses in the form of racks and beams;
- as a material for external and internal walls of wooden houses;
- for the device of stairs, fences, etc.
Bar
It differs from a bar in that the maximum size of its section is 75 mm. Like timber, it is most often made with a square section.
Used for interior work such as the device:
- stairs;
- railings;
- window sills;
- bases for finishing plating;
- roof counter battens.
How to calculate the number of boards in a cube
Edged board
As you know from the course of high school, the volume of a rectangular parallelepiped (and the edged board, timber and bar - this is it) is equal to the product of the lengths of its sides.
Calculated by formula 1:
where: V is the volume; L - length; b - width; h is the height (in our case, the thickness) of the board.
Having calculated the volume in this way, you can easily find the number of boards in a cube.
To do this, you need to divide the unit by the resulting number (formula 2):
where: N - number of pieces, 1 - 1 cub. m, V - volume.
It should not be forgotten that the dimensions of the edged materials are given in millimeters, therefore, they must be converted into meters before calculating.
Example
There is lumber with the following parameters:
25 × 150 × 6000, where 25 is the thickness; 150 - width; 6000 - length.
Let's calculate the cubic capacity of the board.
To do this, we convert millimeters to meters and substitute the obtained values into formula 1:
V = 0.025 × 0.15 × 6 = 0.0225
Substitute the resulting number into formula 2:
N = 1 ÷ 0.0225 = 44.4
The result is always rounded to whole numbers by discarding the decimal part.
Thus, one cube contains 44 complete boards.
Unedged board
In this case, it is more difficult to solve the previous problem.
An unedged one has a large difference in width on opposite faces, therefore, when calculating the volume, the average width must be substituted in formula 1: these two widths are added and the resulting amount is divided in half.
The measurement result is rounded to 10 mm, fractions up to 5 mm are not taken into account, and fractions of 5 mm or more are considered 10 mm.
In addition, uncut edges prevent the board from being tightly packed, and various multipliers are used to calculate the exact volume.
The calculation method is not so much difficult as tedious, so it is easier to use the table from the next section.
Grooved board and lining
They differ from each other only in size, so the calculation method is the same for them.
They are mounted according to the tongue-and-groove system, as shown in the figure.
For the width b in this case, the so-called "working" or "visible" width is taken - the distance from the base of the tongue to the edge of the board (see Fig.). It is this size that should be substituted in formula 1.
Tables of the number of boards in a cube
In order not to calculate the quantity and volume each time, special cubic tables were compiled, in which for each size of material its quantity in one cubic meter is given.
4 meter boards
6 meter boards
4-meter bar
6 meter beam
Unedged material
Due to the wide range of sizes in length, thickness and width, it is impossible to calculate the exact amount of slab in one cube, so there is no cubature table for it.
Here is a table for converting the fold volume of the slab into a dense one.
In this case, we solve the inverse problem: we determine what the actual volume has a known amount of slab.
For this you need:
- Dismantle the croaker into a barked one (from which the thickest end, closest to the tree root, has been removed) and unbarked.
- Sort by length - up to 2 meters and more than 2 meters.
- Sort by thickness if necessary.
- Place in a bag alternating thin and thick ends.
- Calculate the fold volume of the bag.
- Select the appropriate factor from the table and determine the actual (dense) volume.
Cubature for unedged boards.
Coverage area calculation
When the main construction is completed, it's time to start finishing work: sheathing the walls and laying clean floors.
To do this, recall the formula 1. Calculating the volume of one element, we write down the intermediate result - the product:
where S is the area of this element.
Having calculated the quantity according to the formula 2, we multiply the result obtained by the area.
