Question

Find the surface area of the prism

Answer 1

The answer is 152.5 ft

Explanation:

What I did as multiply 6x2.5 and didn't divide by 2 because there are 2 of those triangles and got 15

Then I multiplied 6.5x11 and added that to 6x11 and got 137.5

After that I added 137.5 and 15 to get my answer of 152.5
