In order to calculate the surface area of a triangular prism, you need to know the formulas for the area of a triangle and the area of a rectangle.
The formula for the surface area of a triangular prism is:
SA = 2(base area of triangle) + (perimeter of base triangle) * (height of prism)
To calculate the base area of the triangle (1/2 base * height) and the perimeter of the base triangle (sum of all side lengths of the triangle), you need to know the measurements of the triangle.
Once you have these measurements, you can plug them into the formula to calculate the surface area of the triangular prism.
3. Calculate the surface area of the triangular prism below.
