Since it's a cube, the length, height, and width are all the same,
and we just speak of an "edge" and call it "e".

V+=+e%5E3
48+=+e%5E3
Take cube roots of both sides:
root%283%2C48%29=root%283%2Ce%5E3%29
root%283%2C8%2A6%29=e
root%283%2C8%29%2Aroot%283%2C6%29=e
2%2Aroot%283%2C6%29=e

So each edge of the cube is 2%2Aroot%283%2C6%29.
And the edge is the same as the length, height, and width.

A cube has all sides equal. So the cube root of 48 is the length, wide and height
Find the factors.
8*6
2*cube root of (6)
