    1. The problem statement, all variables and given/known data

    The floor of a room measures 6.0 m x 4.0 m. Calculate its area in m^2, cm^2 and mm^2. The room height is 3.0. Calculate its volume in m^3, cm^3 and mm^3.

    2. Relevant equations
    centi = 10^-2
    milli = 10^-3

    3. The attempt at a solution
    To get it into cm^2 and mm^3 i tried multiplying the numbers by the value of centi and milli but this is wrong. Please could you show me how to do it and explain why :D
    Thank you so much! x

    If 100 centimeter = 1 meter, then the ratio 100cm/1m = 1, correct? What happens if you square both sides?
