The sum of the lengths of all the edges of the cube is 36 cm. What is its volume?

The cube has 12 edges of the same length. If you know the sum of all edges, you can find the length of one edge:

36: 12 = 3 cm – cube edge.

The volume of the cube is calculated by the formula:

V cube = a3, where V cube is the volume of the cube, and is the edge of the cube.

Therefore, the volume of our cube:

V cube = 33 = 27 cm3
