Answer 1

Pyramid A is a square pyramid with a base side length of 18 inches and a height of 9 inches. Pyramid B has a volume of 3136 cubic inches. How many times bigger is the volume of pyramid B than pyramid A? Give your answer as a percent. Provide an explanation and proof for your answer to receive full credit.

Answer 2

Pyramid A = 1/3(B)(H)
Pyramid B = volume of 3136 cubic inches

Pyramid A = 1/3(18)(9) =

Answer 3

Calculate the volume for pyramid A and you already have the volume of pyramid B. After doing that, divide volume of pyramid B by pyramid A.

After you divide the volumes time it by a 100 you will get the percentage.

Answer 4

I understand that part haha but don't really get the formula for it? 1/3(18)(9) isn't it?

Answer 5

18 * 9 = 162 / 3 = 54. 3136 / 54 = 58.07. Doesn't seem right to me? @Boblovesmath

Answer 6

Lets do it together, what do you think?

Answer 7

Ok

Answer 8

find the volume for pyramid A, whats the formula?

Answer 9

v = 1/3 (b)^2(h)
v = 1/3(18)^2(9) = 972
v = 3136 / 972 = 3.226

Answer 10

Okay so Pyramid A is about 3 times bigger than Pyramid B. Times it by a hundred you would get a percentage.

Answer 11

322% ?
