Question

Just want to check my answer :)

Pyramid A is a square pyramid with a base side length of 14 inches and a height of 6 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 1

my answer - volume of sq pyramid=1/3 b^2*h

volume of pyramid A = 1/3 * 196 * 6 =196*2 =392
Pyramid B has a volume of 3136 cubic inches vol...a/b =3136/392=8times
percent change = 392/3136 * 100 =12.5%

Answer 2

i think that's true

Answer 3

this is kinda ambiguous. It's asking *how many times* bigger.

Answer 4

So i don't think it's asking for percent increase

Answer 5

So i am wrong? just wondering?

Answer 6

I would go for 8 times bigger.

Answer 7

But it is asking for a percent :) so would it be 12.5% or 800%

Answer 8

well, 8 = 800%

Answer 9

percentage can mean different things depends on the context.
so 800% doesn't mean 800% more but rather 800% of the volume of A

Answer 10

lol so I am just going to switch it at the end to 3136/392 * 100 =800 ? right?

Answer 11

you probably meant 3136/392 = 800%

Answer 12
