Answer:
21 in
Step-by-step explanation:
by the Pythagorean theorem we have

The volume of a cube is found by cubing the edge length — or multiplying it by itself twice.
In other words, the volume of a cube is as follows:

Simplified:

To find the edge length from the volume, you'd have to do the opposite, which is to find the cubic root.
