A cube shaped cage measures 5 units on each side.  To find the amount of space the  cage occupies (volume)  find the cube of the measure of one side of the bird cage.  Express the amount of space occupied by the cage as a power.  Then find the amount in cubic units.

Volume - length x width x height

Volume  =  5         x    5      x  5
