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. (10 points)

answer:

800%

step-by-step explanation:

so for pyramid a:

use s×s×h×1÷3

so 14×14×6×1÷3, so you get 392.

so to find how many times bigger pyramid b is divide 3136 by 392 to get 8, so it would be 800%

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
