Question

PLEASE HEP.
A briefcase measures 30 cm wide, 45 cm long and 14 cm tall. Which is the correct unit of measurement to use when describing the amount of space inside of the briefcase? A. cm B. cm² C. cm³

Answer 1

C because you have three number and volume requires 3 numbers therefore you use ³

Answer 2

C. cm^3, because cm is the length of a line and then cm^2 is the size of a flat object. And if you add height you now have the volume inside of the container, and since it is not being filled with a liquid cm^3 would make the most sense. Also, it is the only choice left when you eliminate the other two.
