Answer:
A.) 33
Explanation:
You need to find the areas of all the shapes in the triangular prisms and the add them all up...
Front right triangle
A = b * h /2 ÷ 2
A = 2 * 3/2 ÷ 2
A = 3 ÷ 2
A = 3/2 or 1.5
The back triangle will be the same as the front triangle which is 1.5.
Rectangle at the back
A = b * h
A = 3/2 * 5
A = 7.5
The bottom rectangle
A = b * h
A = 5 * 2
A = 10
The top rectangle
A = b * h
A = 5 * 5/2
A = 12.5
Now that we have all the areas for all of the sides, we need to add them all up to get the surface areas for the triangular prism.
1.5 + 1.5 + 7.5 + 10 + 12.5 = 33
The surface area for the triangular prism is 33
Hope this helped!
