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

[tex]\frac{A}{B}=\frac{200}{800}=\frac{1}{4}[/tex]

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

[tex]\frac{A}{B}=\frac{1}{4}\\\\4A=B[/tex]

Hence, B is 4 times the volume of A
