The answer would be 434 ft squared. Find the area of all six sides, then add them up. 17 x 5 = 85. 17 x 6 = 102. 6 x 5 = 30. Each of these values will be added twice, as there is another side identical to them on the opposite side of the rectangular prism. So, 85 + 85 + 102 +102 +30 + 30 = 434. Thus you get your answer of 434 ft^2.
