Question

Find the surface area of the prism ​

Answer 1

Answer:

136 $m^{2}$

Step-by-step explanation:

Well if you find the lateral area (the area of the rectangles on the sides) to get 112, so you just need to add that to the triangles and for those (they add up to 36) you can just use the formula for the area of a triangle,  which is $b*h/2$.

Hope this helps :)
