Question

What is the surface area of this right triangular prism?

Enter your answer in the box.

(Answer) in²

Answer 1

I think it’s
1200 in2

find out the bottom which is a rectangle so 30x15=450

find out the triangle in the middle and back so you work out half of the whole rectangle so 15x8=120x2=240

and work out the triangles above so 15x17=255x2=510

add up 510+240+450=1200
