Question

A cube has a volume of 27 squared feet. What is the length of each side?

Answer 1

Hello!

The formula for volume of a cube is $V= a^{3}$; you are given the volume, so plug it into the formula for $V$.

$V= a^{3}$
$27= a^{3}$

Take the cube root of each side:

$27= a^{3}$
$\sqrt[3]{27} = a^{3}$
$3=a$

Answer:
The length of each side is 3 cubic feet.

Answer 2

using formula v=a^3
a=v^1/5=27^1/5=3
 to checking your answer 
             v=a^3
                   3^3
                     27
the answer for your question is 3
