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 3,136 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.

I'm looking for the answer to that question too. You can look on other links because they have the same question.

Pyramid B is about 107.54% bigger than Pyramid A.

Step-by-step explanation:

1) Plug the numbers into the formula:

1/3 (18) (9) = 2916 cubic in.

2) Now divide the volume of Pyramid B but

the volume of Pyramid A:

3136 / 2916 = 1.07544582

3) Multiply the result by 100 or simply move

the decimal over 2 places:

1.07544582 x 100 = 107.544582%

4) Instead of writing the whole percentage,

I just rounded to the nearest

hundredth:

107.54%

That’s it!! I’m pretty sure it’s correct and if it’s not, I apologise. I’ve searched for the answer too but couldn’t find one and this is how I solved the problem.
