For easy calculation and presentation of answer, I will convert all the fractions here to decimals: 2 1/2 = 2.5 ft 1 1/2 = 1/5 ft 3 1/2 = 3.5 ft
------------------------------------- Find Surface Area : ------------------------------------- Surface Area = 2(2.5 x 1.5) + 2(1.5 x 3.5) + 2(3.5 x 2.5) Surface Area = 7.5 + 10.5 + 17.5 Surface Area = 35.5 ft² (Decimals) or 35 /12 ft² (Fraction)
-------------------------------------------------------------------------- Answer: Surface Area = 35 1/2 ft² --------------------------------------------------------------------------
