Answer:

B is 4x bigger than A

Step-by-step explanation:

-This is a question testing proportionality.

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

$\frac{A}{B}=\frac{200}{800}=\frac{1}{4}$

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

$\frac{A}{B}=\frac{1}{4}\\\\4A=B$

Hence, B is 4 times the volume of A
