    another hint: if you square both sides of 10 mm = 1 cm, you get 100 mm^2 = 1 cm^2

    the actual area doesn't change imagine a pool of water. The amount of water doesn't change based on what measurement units you use. but since 1 cm^2 = 100 mm^2, this means that you multiply by 100 to convert from cm^2 to mm^2
