Answer 3

the formula for any triangular prism is bh+2ls+lb
b=area of the base
l=length
h=height

Answer 4

If that doesn't make sense to you, then try area of three rectangles + area of the two triangles

in this case it would be (13*8) + (5*8) + (12*8) for the rectangles
and (12*5)/2 for the triangles
then add the answer todether
