First find the range in inches, because those are easier to change in to feet.
13.5 times 0.39 = 5.265 I took the centimeters, and changed them in to inches by multiplying 13.5 by 0.39
I know that each foot is 12 inches, so I do 12 divided by 5.265 and i get 2.27 (rounding to the nearest hundredth)
the answer is 2.27 feet.
