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:

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.
