Answer:
A. 862.4 in^2
Explanation:
1) (14x8.9)=124.6
124.6x4(4 sides have the same surface area)=498.4
2) 13x7(half of the 14in)=91
3) Typically, to find the surface area of a right triangle, you would divide the answer by 2, but since we have 8 right triangles, we can just multiply the 91 by 4. 91x4=364
4) 364+498.4=862.4 in^2
