The total surface area of the rectangular box shown below is the sum of the areas of the 6 sides. What is the box's total surface area, in square inches? F. 12 G. 16 H. 20 J. 24 K. 32 The correct answer is K. Explanation: The top and bottom are 2 by 2 so each has area 4, so 2(4) = 8. The front and back are 2 by 3 so each has area 6, so 2(6) = 12. The sides are 2 by 3 so each has area 6, so 2(6) = 12. The total surface area is 8 + 12 + 12 = 32.
