Question

n edge of Cube A is 8 inches, and an edge of Cube B is 5 inches. To the nearest tenth, how many times greater is the volume of Cube A than Cube B?

Answer 1

4.1 times greater

Explanation:

The formula of a volume of a cube:

`V=a^3`

a - edge

Cube A:

a = 8in. Substitute:

`V_A=8^3=512\ in^3`

Cube B:

a = 5in. Substitute:

`V=5^3=125\ in^3`

`(V_A)/(V_B)=(512)/(125)=4.096\approx4.1`
