One valid method for calculating the surface area of a triangular prism is to find the area of each of the three faces of the prism (two triangular faces and three rectangular faces), and then add them all together.
The formula for finding the area of a triangular face is (1/2) * base * height, and the formula for finding the area of a rectangular face is length * width.
Once you have found the area of each face, you can add them together to get the total surface area of the triangular prism.
