Volume = l x w x h

As it is a cube, all the lengths would be the same

Substitute in the value you have:

480 = l^3

(it would be cubed as it is the same value multiplied by itself twice (3 numbers))

Cube root it:

l = 4.829735282

The final answer is 4.82 inches

Hope This Helps You!

Good Luck (:

Have A Great Day ^-^
