How to find the edge length of a cube with a volume of 27 cm3 and 125 cm3.

To find the length of an edge of a cube if the volume of the cube is known.

We know that the volume of a cube is the length multiplied by the width and multiplied by the height of the cube, and since in a cube, the height, length and width are equal, so the volume of the cube is a number in the third power.

So we need to decompose the volume of the cube into three equal factors.

If the volume of the cube is 27 cm 3, then we need:

3 * 3 * 3 = 27,

3 * 3 = 9;

9 * 3 = 27.

And if the volume of the cube is 125 cm 3, then we need:

5 * 5 * 5 = 125.

5 * 5 = 25;

25 * 5 = 125.
