Question

If the volume for 3-D polyhedra A is 200 cm3 and the volume for 3-D polyhedral B is 800 cm3, how many times bigger is the volume of pyramid B than pyramid A?

Answer 1

B is 4x bigger than A

Explanation:

-This is a question testing proportionality.

#We first get the ratio the ration of the volumes as

`(A)/(B)=(200)/(800)=(1)/(4)`

We then express it in the equation form of constant of proportionality y=kx, where k is the constant of proportionality:

`(A)/(B)=(1)/(4)\\\\4A=B`

Hence, B is 4 times the volume of A
