Answer:
184 cm^2
Step-by-step explanation:
The surface area of the triangular prism is found by adding up the areas of the sides
We have two triangular bases
A = 1/2 bh
= 1/2 (6) * 4 = 12
But there are 2 of them so multiply by 2
2*12 = 24
We have 2 sides that are rectangles
A = l*w
A = 5*10 = 50
There are 2 so multiply by 2
2*50 =100
We have the one rectangle that the figure is resting on
A = b*w= 6*10=60
Add all five areas together
2 triangles + 2 sides + 1 bottom
24+ 100 + 60
184 cm^2
