Pentagonal Prism Formula 1  : Area of Base(A) = Â½ * a * 5 * s Perimeter of Base(P) = 5s Surface Area of Prism = 5as + 5sh = 5as + Ph Volume of Prism = (5/2)ash = Ah. 2  a = apothem length, s = side, h = height.
Surface Area of a Prism. The surface area S of a prism is the sum of the areas of the bases and. the lateral faces. S = areas of bases + areas of lateral faces. EXAMPLE 2 Finding the Surface Area of a Triangular Prism. Find the surface area of the prism. Draw a net. 4 m. 3 m. 5 m.
