Find the volume of a cube with an edge of 20 cm. Express in liters

Since the answer is required to be given in liters, we translate the length of the cube edge from centimeters to decimeters:

20 cm = 2 dm.

The volume of a cube is equal to the cube of the length of the edge:

2 ^ 3 = 8 (dm3).

1 dm3 is equal to 1 liter, therefore the volume of this cube in liters is 8 liters.

Answer: the volume of the cube is 8 liters.
