Question

The area of the face of a cube is 9 square centimeters. Use 9 of these cubes to make a rectangular prism. What is the volume of the rectangular prism

Answer 1

243 cm^3

Explanation:

The faces of a cube are squares.

A = s^2

s^2 = 9 cm^2

s = 3 cm

The side of the square is the edge of the cube and is 3 cm.

V = s^3

V = (3 cm)^3 = (3 cm)(3 cm)(3 cm) = 27 cm^3

The volume of one cube is 27 cm^3.

The volume of 9 cubes is 9 * 27 cm^3 = 243 cm^3

Answer: 243 cm^3
