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 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 to receive full credit.

Pyramid B is greater than Pyramid A by 87.5%

Step-by-step explanation:

If a square pyramid has a base edge of 14, then square 14 and multiply by 6. That is 1176 and divide it by 3. That pyramid will have a volume of 392. Then you subtract 392 from 3136 to get 2744 which is 87.5% of 3136, meaning that Pyramid A is only 12.5 % of the volume and the answer is 87.5%.
