Find the volume of a rectangular parallelepiped with dimensions 5 cm, 4 cm and 8 cm.

Given:

a = 5 cm;

b = 4 cm;

s = 8 cm;

V =? cm³;

At the base of the parallelepiped lies a parallelogram. Parallelogram, as known, the opposite sides are parallel and equal. A box is a three-dimensional shape, a three-dimensional polyhedron, where each face is a rectangle. There are six such faces – rectangles.

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

V = a * b * c = 5 * 4 * 8 = 160 (cm³)

Answer: 160 cm³ is the volume of a rectangular parallelepiped.
