The correct method for calculating the surface area of a triangular prism is to find the area of the two triangular bases and the three rectangular faces separately, then add them all together.
The formula for calculating the surface area of a triangular prism is:
Surface Area = 2(base area of the triangle) + (perimeter of the triangle)(height of the prism)
To find the area of the triangular bases, you can use the formula:
Base Area = (1/2)(base length)(height of the triangle)
To find the area of the rectangular faces, you can use the formula:
Rectangular Face Area = (height of the prism)(width of the face)
After finding the areas of all the faces, you can add them together to get the total surface area of the triangular prism.
