All about the cubic meter of lumber

Not a single construction site can do without lumber, but the most important thing is the correct calculation of the amount of timber or boards required. The success of the construction and the speed of the work depends on this. To avoid performing calculations from scratch, it is recommended to use a cubature box.

A cubicle is called a table that makes it possible to calculate the amount of lumber, usually it is round wood. At the same time, the dimensions of the material must strictly comply with all the requirements of GOST for the convenience of transportation, storage and processing. But even so, there is waste that, when trimmed and cut, does not go into construction.

The cubes and tables help determine the exact amount of materials needed to complete a project. It is easy to guess that it will be different for an economic block, a shed or a bath, not to mention low-rise private houses and cottages. The tables will also help you navigate the combination of weight, volume and size of materials.

When simplifying calculations, a special construction calculator is sometimes used, where all the necessary data are programmed and entered. But if you need to understand how to use tables, and the data, unlike a calculator, are at hand, you should pay attention to the basic formula and understand the features of the calculations.

In order to use the cubic capacity calculator, you need to calculate according to the formula for determining the volume: multiply the height, length and width of the product among themselves. The formula is universal for both boards and round timber, so even a beginner in construction will be able to calculate correctly. The cubic table makes it possible to calculate several more parameters important for construction as quickly as possible:

• content of building material or product in a cubic meter;
• the content of running meters in one cubic meter per area;
• the volume of the entire product as a whole;
• product area.

All these parameters are very important when drawing up a construction project, regardless of the type of structure and its complexity. This gives sufficient accuracy to calculate the required amount of resources, and as a result, the developer does not have to spend money on the purchase of additional materials. Also, the volume and dimensions of wood affect its price. When choosing, it is taken into account whether you need a timber or a board, a type of wood, size and level of quality.

Cubature measurement table makes it easy to determine the exact number of boards or timber in 1 m3. The tables enable the developer not only not to be mistaken in the dimensions of the products, but also to take into account the weight. For the correct choice of lumber on the floor, based on these parameters, it is recommended to consider wood of different species. Conifers are especially popular.

Types of lumber can be different in their properties and characteristics. Sizes also change: there are not only standard edged boards of 4 meters and 6 meters, the calculations for which are given in the tables, but also for 3 or 5 meters inclusive. You can select lumber individually according to the required dimensions, but you need to take into account how much it weighs and how many pieces will be needed for building and implementing a specific project. In addition to timber and boards, experts also pay attention to other raw materials.

• Obapol - has a partially sawn inner face, it is usually used for fastening in the mountains and during the development of a site. In contrast to the standard processing of the board, the material has no external sawn-through cavity.
• Humpback obapol - on the contrary, the outer part of it is sawn about half of its total length.
• Obapol boardwalk is sawn from the outside almost completely, leaving about a third of the untouched area.
• Slab - a round log, sawn either on one side, or partially. For such products, the thickness and width are usually normalized from the side of sharp, thin ends.
• Slab board with sawn partly outer surface.

It is very important to understand the difference, as the scope of application of these materials will also change as a result; some believe that they do not differ from each other, which is a gross mistake. But it is worth considering that the scope of the same obapol is much narrower than the slab. The latter is used for several purposes:

• in the manufacture of a subfloor;
• during roof lathing;
• if necessary, the manufacture of formwork.

Beams - lumber, the thickness of which starts from 100 mm, the height of the section of the bar and its width also differ. But usually the difference between the parameters does not exceed the value twice. Beams are more often used in the construction of frame or wooden houses, as well as in the arrangement of stairs and fences directly inside the premises. Sometimes a bar with a smaller diameter section is also used: exactly 75 mm. When calculating the volume, the thickness, average width and height of the bar are taken into account. After that, you can calculate the amount of timber per area by dividing the desired parameter by one. But it is much easier to use special tables than to calculate the data yourself or check the calculations using the data from the tables directly at the final stage.

As for the price of building materials, based on the received calculations, the situation here is interesting. When choosing a material, it is very important to pay attention to the type of board or timber, since this will change the cost of raw materials. And the price of the required volume, respectively, is calculated by multiplying by a cubic meter. It is worth remembering that when calculating the cubic capacity, it is customary to round numbers to whole values. Therefore, the price of 1 board of a specific material may be different than the entire price per cubic meter. In addition, the length of the board also matters. It is good if you manage to purchase a board or timber with a standard length of 6 or 4 m, but the error can be different, and it is not taken into account when taking into account the volume and forming a pricing policy. Ultimately, the price of lumber can increase by 1-2%. This error must be taken into account when buying a large number of boards or timber for construction.

With a bar and an unedged board, the pricing policy is formed in exactly the same way, the values ​​are rounded, and the average width at the ends is taken to calculate the volume. This assumes that the length of the material will be approximately the same. All calculations can be carried out using a regular tape measure, but when measuring timber and different types of boards, there are always subtleties.

As for the boards, it is important to understand this: edged board and unedged board differ from each other. And each of these types has its own standard sizes and its own field of application. For an uncut board, the thickness can be from 25 to 50 mm with a standard length of 6 meters. Such boards are well suited for temporary fences and utility rooms. They are used as a base for cladding with other finishing materials and are additionally processed.

Edged board propylene on the face and edge and is used more widely, even for the manufacture of all kinds of cabinet-type country furniture.Anyone who is familiar with the high school mathematics course will be able to calculate the amount and amount of materials required. To do this, it is enough to multiply the length, width and thickness of the board among themselves, and to get exactly the number of boards, you need to divide the unit by the resulting volume. For example, with a thickness of 25 mm, a width of 150 and a length of 6000, the total volume or cubic capacity of lumber will be 0.0225. And dividing the unit by the resulting value, it turns out that we need 44 whole boards for building without residues and scraps.

At an uncut board calculations are carried out in exactly the same way, only you need to take into account a small difference in width, since it is not cut in the same way on the seams. For calculations, its average value is used, the width is added on both sides, then the resulting value is divided in half. The result is certainly rounded to an even number, but in order not to carry out calculations manually, you can always use special tables.
