Question 20
H

A cube of a solid is cut up so that the length of each side decreases by a factor of 100.

What happens to the surface area to volume ratio of each piece, and why?

[1]
A

It decreases by a factor of 100, because the volume falls faster than the surface area

B

It decreases by a factor of 100, because the surface area falls faster than the volume

C

It increases by a factor of 100, because the surface area falls faster than the volume

D

It increases by a factor of 100, because the volume falls faster than the surface area
