Question

What is the volume of four cubes with a side length of fraction 1 over 4 foot? V = s3, where s is the side length.

A. fraction 1 over 4 ft3
B. fraction 1 over 3 ft3
C. fraction 1 over 12 ft3
D. fraction 1 over 16 ft3

Answer 1

D. fraction 1 over 16 ft³

Explanation:

The formula of a volume of a cube:

V = s³

s - side length

We have s = 1/4 ft. Substitute:

V = (1/4)³ = 1/64 ft³

We have four cubes.

4V = 4 · 1/64 = 1/16 ft³
