Answer 2

Check the picture below.

so the prism is really just two triangles and three rectangles, so

`\stackrel{ \textit{\LARGE Areas} }{\stackrel{ two~triangles }{2\left[\cfrac{1}{2}(\underset{b}{8})(\underset{ h }{3}) \right]}~~ + ~~\stackrel{ two~rectangles }{2(4)(5)}~~ + ~~\stackrel{ rectangle }{(8)(4)}}\implies 24+40+32\implies \text{\LARGE 96}~in^2`
