How do you calculate the square feet of a roll of paper towels?

To calculate the square feet of a roll of paper towels, first determine the dimensions of the roll. Measure the width of the paper towel (in feet) and the length of the roll (also in feet). Multiply these two measurements together: Square Feet = Width (ft) × Length (ft). If the length is given in yards or inches, convert it to feet before performing the calculation.
