1. The problem statement, all variables and given/known data How many square centimeters are in 2.5 ft^2 ? Known: 1 inch≡2.54 cm 1 foot≡ 12 inches 2. Relevant equations 3. The attempt at a solution 2.5 ft^2/1 x 12in/1ft x 2.54cm/1in = 76.2 cm I tried converting 2.5 ft^2 to centimeters by using dimensional analysis. However, I realized that it doesn't take into account that it is 2.5ft^2 not 2.5 ft. I don't know how to convert it to centimeters squared, rather than just cm.
