Question

The net below is folded on the lines to make the triangular prism. What is the surface area of the prism?

Answer 1

184 square inches

Explanation:

So first, we find the area of the triangles. It has base of 6 and a height of 4, so 1/2 (6) (4) we get 12. We double that so we have both triangle's area (24) Then we find the area of the 3 rectangles. two of the rectangles are 5*10, and one is 6*10. so 2(5*10) = 100, and 6*10 = 60. now we add all the values up to get

24 + 100 + 60= 184

The surface area of the triangular prism is 184 square inches
