Advice 1: How to find volume using area

Volume – a measure of capacity, expressed as geometric shapes in a formula V=l*b*h. Where l – length, b – width, h – height of the object. If you only have one or two characteristics to calculate the volume in most cases impossible. However, under certain conditions it is possible to make it through the area.
How to find volume using area
Task one: calculate the volume, knowing the height and area. This is a simple task, because the area (S) is the product of length and width (S= l*(b), and the volume is the product of length, width and height. Substitute in the formula for volume is l*b area. You will get an expression V=S*h.Example: the Area of one side of the parallelepiped is 36 cm2, height 10 cm Find the volume of the parallelepiped.V = 36 cm2 x 10 cm = 360 cm3.Answer: the volume of the parallelepiped is equal to 360 cm3.
Task two: calculate volume knowing only area. This is possible if you calculate the volume of a cube knowing the area of one of its faces. Because the edges of the cube are equal, then removing from the value of the square of the square root, you get the length of one edge. This length will be the height and width.Example: the area of one face of a cube is 36 cm2. Calculate the volume.Extract the square root of 36 cm2. You've got a length of 6 cm For a cube the formula will be: V = a3, where a is the edge of the cube. Or V = S*a, where S is the area of one side, and the edge (height) of the cube.V = 36 cm 2 * 6 cm = 216 cm3. Or V = 63cm = 216 cm3.Answer: the Volume of a cube is 216 cm3.
Task three: calculate volume if we know the area and some other conditions. Conditions can be different, in addition to the area may be aware of other options. Length or width can be equal to height, more or less than the height several times. May also be given additional information about the figures that will help in the volume calculations.Example 1: find the volume of the prism if you know the area of one side of 60 cm2, a length of 10 cm and a height equal to the width.S = l * b; l = S : b
l = 60 cm 2 : 10 cm = 6 cm width of the prism. Because the width and height, calculate the volume:
V = 10 cm * 6 cm *6 cm = 360 см3Ответ:the volume of the prism is 360 cm3
Example 2: find the volume of the figure if the area of 28 cm2, the length of the figure 7, see Additional condition: four sides equal, and are connected to each other in width.For the solution you want to build a box. l = S : b
l = 28 cm2 7 cm = 4 cm – shiranakatta side is a rectangle whose length is 7 cm and width 4 cm If four such rectangle to interconnect width, we get a parallelepiped. The length and width in it at 7 cm and height 4 cm V = 7 cm * 7 cm * 4 cm = 196 см3Ответ: Volume of parallelepiped = 196 cm3.

Advice 2 : How to calculate the volume of the room

The person buying a new apartment, it usually has little interest in the volumeω. It was much more interested in the area. To know the area necessary for arrangement of furniture, and to calculate the communal areas. But there comes a point when the landlord wants to buy an air conditioner and asks himself the question, what is so required of the device must be power. The capacity is calculated from the volume of the room. To calculate the amount of space you may need and in the design of children's and public institutions, when each visitor health standards must have a certain number of cubic meters of air.

To calculate the volume of the room is rectangular in shape, no special tricks are required. It is sufficient to measure and multiply length, width and height. The only thing to care about accuracy. The tool needs to be believed. It is better to conduct measurements on the wall is strictly vertical and strictly horizontal line, because if you measure the length of the baseboard, you can get the error. Lines can be drawn with the help of a level and metal square. Stay tuned to the beginning of the line exactly coincide with the zero mark of the measuring tape.
If the room has projections, recesses, ventilation ducts and other objects, you must divide it into zones. In the room with a niche swipe across the floor straight line, cutting a niche. Measure first parameters greater part of the room and calculate the volume. Then just measure the gap, multiply the measurements and add the resulting amount to the volume of other premises. If the main part of the room and the niche the same height, the vertical measurements a second time to remove, of course, makes no sense. If the height is different, you'll have to do it.
If the room has, for example, a mezzanine or a ventilation box, which "eats" part of the volume, it is necessary to measure them. This is done exactly the same as the dimension of the room, only the resulting number should be subtracted from the total volume of the room.
Some more problems can occur with non-rectangular room shapes. If you need to calculate the volume of a round veranda or attic, try to accurately calculate the area of the floor. Find a center swipe through a few radii and measure one of them. For testing, you can measure all the radii, they must be the same. The porch floor trapezoidal shape, divide the straight lines on the rectangle and 2 triangles. It will be much easier to calculate the area, rather than to remember the formula for area of a trapezoid. Fold along the area of the rectangle and triangles and then multiply all this at the height of the room.

Measurements more convenient to perform together.

Advice 3 : How to calculate building volume

The definition of construction volumes, it is important to calculate the cost of the project. Statement on the counting of quantities is the main document when determining the estimated cost of the entire building. So how can one calculate the building volume?
How to calculate building volume
For compilation of bills of quantities use of normative documents, technical manuals, instructions and other technical documents. The estimates of the works recommended on the proven schemes that visualize the progress of calculations, as well as all the sequence of their production. For this fit certain rules.
Building volume of the basement determine by multiplying the cross-sectional area of the basement horizontally at the level of the ground floor, measuring above the cap height from the floor level to the same level floor from the lower floor. If the basement is built inside the building without the walls above it, calculates area (external stroke the walls at the ceiling above the basement.
Building volume the upper, terrestrial part of the house with attic ceilings define by multiplying the area of the horizontal cross section of the external border of the structure (including the thickness of the veneer, stucco) in the lower floor above the basement to the full height of the building, measured from the floor level from the ground floor to the top of the insulation on the attic floor.
To determine the amount of the ground part of the house without garret overlapping, multiply the area of cross-section vertical to the length of the building, which is measure between the outer surfaces of the opposite end walls perpendicular to the cross-sectional area at the level of the ground floor above the basement. The cross-sectional area calculate the perimeter on the outer surface of the walls, and given the upper contours of the roof and the floor level from the ground floor.
If the building has projecting parts and niches, in the measurement of the cross section are not taken into account. If the floors have a different area, then the volume of the building define as the sum of its parts. In addition, we expect the volume of the individual parts of the building, if they are significantly different in form. In such cases, the delimiting wall consider the part which it corresponds in design or height.
Building capacity building with basement define as the sum of the volumes of the basement and ground parts.
Note that the volume verandas, Bay Windows and other parts that increase the useful volume must be calculated separately and included in total volume. Do not turn on only in the building volume the volume of porches and open balconies.
