Bill has a container that is shaped like a cube. He uses 125 cubes with a side length of 1 inch to fill the container completely
Annette [7]

Answer:

5 inches

Step-by-step explanation:

Given

Length of a cube = 1 inch

Required

Determine the edge length of the cube

If the container can take 125 cubes, then that's the volume

So:

Volume = 125in^3

Volume of a cube is calculated as thus;

Volume = Length^3

This gives;

Length^3 = 125

Take cube root of both sides

Length = \sqrt[3]{125}

Length = 5

Hence, the length is 5 inches
