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.
Find the total surface area of an isosceles trapezoidal prism with parallel edges of the base 6 cm and 12 cm, the legs of the base 5 cm each, the altitude of the base 4 cm and height of the prism 10 cm.he lateral surface area of a prism is the sum of the areas of its lateral faces. The total surface area of a prism is the sum of the areas of its lateral faces and its two bases. Usually, if right or oblique is not mentioned, you can assume the prism is a right prism.
