Answer
$8$ ft.$^3$
Work Step by Step
The dimensions of a cube are all the same; therefore, we can cube $24$ in. and get the volume of the cube. We want the answer in cubic feet. We can actually convert the dimensions to feet already. There are $12$ inches in a foot; therefore, $24$ inches is equal to $2$ feet.
Let's plug the dimensions into the formula to find volume:
$V = 2^3$ ft.$^3$
Evaluate the exponent:
$V = 8$ ft.$^3$
