Answer: 540 in^2
Step-by-step explanation: Find each area of each shape, then add them up to find the surface area of the triangular prism. The rectangle on the top would be 13 x 16 = 208 in^2. The rectangle in the middle would be 12 x 16 = 192 in^2. The triangles would add up to 60 in^2 since (12 x 5)/2 x 2 is 60. The rectangle on the bottom would be 5 x 16 = 80 in^2.
