Answer: Pyramid A = 972 cubic inches
Pyramid B is 322% bigger than Pyramid A
Pyramid A has the following data
The base of the pyramid = 18 inches
The height of the pyramid = 9 inches
Volume= area x (height/3)
The area = length x length
Area = 18 x 18
Area = 324 square inches
Volume = 324 x (9/3)
Volume = 324 x 3
Volume = 972 cubic inches
The volume of pyramid B = 3136 cubic inches
How many times bigger is the volume of pyramid B than Pyramid A
percentage = pyramid B / pyramid A x 100%
= 3136 / 972 x 100
= 3.22 x 100%
= 322%
Therefore, Pyramid B is 322% bigger than Pyramid A
