Answer:
240m
Explanation:
You need to find the area of each surface.
FORMULAS
A= L × W
A= 1/2(L × W)
SIDES
Base = 12×6 = 72
Top of triangle = 6×13 = 78
Side of triangle = 5×6 = 30
Triangular side 1 = 1/2(5×12) = 30
Triangular side 2 = 1/2(5×12) 30
Now you need to add all of the surface areas together.
72+78+30+30+30 = 240
Therefore, the surface area of the triangular prism is 240m.
IM SO SORRY IF THIS DOESN'T MAKE ANY SENSE!
