There is a rectangular prism and pyramid with congruent bases and height. If the volume of the pyramid is 48 in.3 , what is the volume of the prism?
Since the prism and pyramid have congruent bases and height, the volume of the pyramid is 1/3 the volume of the prism.
Given that the volume of the pyramid is 48 in^3, the volume of the prism is 3 * 48 in^3 = 144 in^3.
Therefore, the volume of the prism is 144 in^3.
