Question

A prism has a surface area of 100 cm2. Which sentence describes the effect of measuring the surface area in square millimeters?

A. The surface area increases.

B. The surface area decreases.

C. The surface area stays the same, but the number representing the surface area increases.

D. The surface area stays the same, but the number representing the surface area decreases.

Answer 1

I'd say C

Answer 2

common sense should tell you the surface area does not change. Using a ruler in cm vs mm will not change your rug, for example.
so it has to be C or D

Answer 3

if you know mm are 10 times smaller than cm, you would know it takes more mm to cover the same distance as 1 cm. the number of mm will be bigger.
