Answer:
Each of the side measures 5ft
Step-by-step explanation:
The volume of a cube is L^3
It is also important to state that since it's a cube box, all the sides are equal in length.
Now that we have a volume of L^3, all we need do is to find a number in which when multiplied by itself three times consecutively, it gives 125 I.e the length of a side is simply L
Mathematically, we simply need to find the cube root of 125. The correct answer that fits into this is 5
Thus, our answer is 5ft.
