The surface area of a triangular prism can be calculated by finding the area of each face and adding them up.
The net of a triangular prism consists of 2 triangles and 3 rectangles. The two triangles have a base of 10ft and a height of 8ft (since the height of the triangular prism is 8ft), so the total area of the two triangles is:
2 * (1/2 * 10ft * 8ft) = 80ft²
The three rectangles have dimensions of 10ft by 26ft, 24ft by 26ft, and 10ft by 24ft. The total area of the three rectangles is:
2*(10ft * 26ft) + 24ft*26ft = 232ft²
Therefore, the total surface area of the triangular prism is:
80ft² + 232ft² = 312ft²
So, the surface area of the triangular prism is 312ft².
