The volume of pyramid B is 3.22 time bigger than the pyramid B
Step-by-step explanation:
Pyramid A:
Base length = 18 in.
Height = 9 in.
Volume = (1/3) (18 x 18) 9
= (1/3) (324) 9
= 972 cubic inches
Volume of pyramid B = 3136 cubic inches
3136/972 = 3.22
The volume of pyramid B is 3.22 time bigger than the pyramid A
Percentage = 322% bigger than the pyramid A
