Find the volume of a rectangular parallelepiped measuring 15 cm 20 cm 30 cm.

Given:

a = 15 cm;

b = 20 cm;

s = 30 cm;

V =? cm³;

A parallelepiped is a three-dimensional geometric figure with a parallelogram at its base. It is a polyhedron that has six faces. Each face is a rectangle.

The volume of a rectangular parallelepiped is calculated by the formula: V = a * b * c, where a is the length, b is the width, and c is the height.

V = a * b * c = 15 * 20 * 30 = 9000 (cm³)

Answer: 9000 cm³ is the volume of a rectangular parallelepiped.
