Russian Dictionary Colier
A direct prism is a body whose two faces (base) are triangles, quadrangles or polygons, and all the rest (lateral) – rectangles (Fig. 104). The rectangular parallelepiped discussed earlier can be classified as a prism: it is a straight prism with rectangular bases. If the bases of a right prism are triangles, then the prism is “triangular”; if it is a square, then the prism is “square”; if quadrangles at all, then “quadrangular”; if any polygons, then “polygonal”, for example. “octagonal”, etc.
We already know how to calculate the volume of a rectangular prism, that is, a rectangular parallelepiped: to do this, we need to multiply its length by its width and height. Since the product of the length of a rectangle by its width gives its area, we can state the previous rule differently, namely this way:
about volumetric rectangular prism
Equal to the product of the area of its base and its height. If the base area of such a prism is denoted by s, and the height – through h, then its volume V= sh.
You can be sure that the same formula applies to any straight prism, no matter what shape its base has. Indeed, for each square centimeter of the base of a straight prism rests a pillar whose height is equal to the height of the prism ( h). All these pillars taken together make up the volume of the prism. But the volume of each column is 1 square. cm H h cm = h cube cm; the number of pillars is equal to the number of squares. cm, contained in the base of the prism. If the base area is 5 sq. cm, then the number of prisms will be s, and the sum of their volumes s? h= sh cube cm. This will be the volume of the prism.
The volume of all direct prisms is equal to the product of area rebuilt at a height.

Applications
31. Calculate the volume of a right triangular prism if its height is 16 cm, and the triangle lying at the base of the prism has a base of 7 cm and a height of 5 cm.
Solution: Let's start calculating the volume by determining the area of the base; it is equal to 0.5 7 5 = 18 square meters. cm. By multiplying the base of the prism by the height, 18 16, we find out its volume - 290 cubic meters. cm.
32. The attic space (Fig. 105) has the shape of a straight triangular prism. Its length is 14 m, its width is 8.1 m, and its ridge height is 3.2 meters. Find the volume (“cubic capacity”) of this room.
Solution: The cubic capacity is 1/2 ? 8,1 ? 3,2 ? 14 = 180 cu. m.
33. What is the area of the base of a straight polyhedral prism, the volume of which is 720 cubic meters? cm, and the height is 18 cm?
Solution: The base is determined by dividing the volume (720) by the height (18). We get 40 cm.
