The total surface area of a triangular prism is the sum of the areas of all its faces: the three lateral faces (rectangles) and two bases (triangles). The most general formula for the surface area of any prism is: Total area = Lateral

Surface Area of Trapezoidal Prism Calculation Formula: S=a (l + h) + b (l + h) + lc + ld where, a, b, c, d are sides of the trapezium. h is Altitude and l = Height of the prism.
