By definition, geometric solids, box is a rectangular parallelepiped or a cube if all its sides are equal. According to a calculation formula of the volume of the parallelepiped is equal to the product of the area of the base to the height.
2
For our example the base of the box, we assume the line which it is on the surface. Let's call it a face ABCD along her sides. 3
According to the theorem the area of a rectangle equals the product of its two sides. Footprint find by measuring two mutually perpendicular sides: AB and BC. Or AD and CD, what is the same, because the parallel sides of a rectangle are equal. 4
The height of the parallelepiped in this case is the edge of the face AE. Finally calculated the volume of the box the formula for the volume of a parallelepiped: (see Fig. 5
This calculates the volume of the box having the form of a rectangular parallelogram, each face of which has the shape of a rectangle. The volume of the box in any other shape will be calculated according to other formulae.
