A cube with a volume of 216 cm3 is cut down to a pyramid with the same size base and the same height as the original cube. What is the volume of the pyramid?
A cube with volume 216 has sides of length 6cm.
The volume of a pyramid is (1/3)*A*h (where A is the area of the base and h is the height of the pyramid).
Therefore, the volume is (1/3)*6*6*6 = 72 cm^3 (answer C).
