Prism volume

From ancient times, people needed to measure the amount of various substances. Bulk substances and liquids could be measured by filling them with vessels of a certain capacity, determining their quantity by volume. The concept of volume in solid geometry is introduced similarly to the concept of area in plane geometry. In plane geometry, we determined the area like this: the area of ​​a polygon is the value of the part of the plane that the polygon occupies. To formulate the concept of volume similarly to this concept. The magnitude of the part of the space occupied by the geometric body is called the volume of this body. Volume is measured in "cubic" units.

Prism — is a polyhedron, two faces of which are congruent (equal) polygons lying in parallel planes, and the remaining faces are parallelograms that have common sides with these polygons. These parallelograms are called the lateral faces of the prism, and the remaining two polygons are called their bases.

The volume of a prism is equal to the product of the area of the base of the prism, by height. where V is the volume of the prism, S is the area of the base of the prism, h is the height of the prism.
