Question

Cecilia has 9 rectangular pyramids that are filled with rice. She wants to transfer the rice into storage containers that are rectangular prisms that have the same size base and height as the rectangular pyramids. How many full storage containers can she fill and have no rice left over?

Answer 1

Well if the bases are the same size, then that must mean the bases have the same area. If the height is the same, then they have the same volume. Since she has 9 of them and they have the same volume, she can fill 9 storage containers with no rice left over.
