What is the volume of the pyramid?
The volume of the pyramid is the product of one-third of the height and square of the base side length.
The volume of Pyramid A = (1/3)(side²)(height)
Pyramid A is a square pyramid with a base side length of 9 inches and a height of 4 inches.
Pyramid B has a volume of 8,100 in3.
The volume of Pyramid A = (1/3)(side²)(height)
= (1/3)(9²)(4)
= 108in³
The volume of Pyramid B is 8,100
The ratio of the volume of A to that of B
= 8100/108
75:1
