The length of the parallelepiped rectangle is R cm, the width is 7 cm, and the height is 9 cm.

The length of the parallelepiped rectangle is R cm, the width is 7 cm, and the height is 9 cm. Calculate the volume if R = 68 cm.

Given:

a = R cm;

b = 7 cm;

s = 9 cm;

V =? cm³;

R = 68 cm.

A parallelepiped is a three-dimensional geometric shape based on a parallelogram. It is a polyhedron with six faces. Each face is a rectangle. The volume of a rectangular parallelepiped is calculated by the formula: V = a * b * c, where a – length, b – width, c – height.

V = a * b * c = 68 * 7 * 9 = 4284 (cm³)

Answer: 4284 cm³ is the volume of a rectangular parallelepiped, if R = 68 cm.
