I'm not reading all of that.
I'm happy for you though.
Or sad that happened.
I apologize for the lengthy response.
The correct method for calculating the surface area of a triangular prism is to decompose the prism into two triangles and three rectangles, and then find the sum of the areas of all five shapes.
