Pyramid a is a square pyramid with a base side length of 9 inches and a height of 10 inches. pyramid b has a volume of 1350 cubic inches. how many times bigger is the volume of pyramid b than pyramid a? give the answer as a percent. provide an explanation and proof for the answer.

In this problem, we just have to compute the volume of pyramid a in order to compare the sizes or volumes of the two pyramids. the volume of the pyramid is equal to 1/3* s^2* h where s is equal to the length of the square base. the volume of pyramid a is 270 cubic inches. the ratio then is equal to 1350/270 equal to 5.
