Why do we measure perimeter in ft, area in ft^2 (or feet squared), and volume in ft^3 (or feet cubed)? What does each mean within the strand of measurement? Why do you think so many students label their measurements with the incorrect exponent?© BrainMass Inc. brainmass.com March 4, 2021, 10:07 pm ad1c9bdddf
We measure perimeter in ft (feet) because perimeter is a measure of length, and it is the sum of lengths having units of ft (or any one-dimensional unit for length), so the units will just remain one-dimensional.
