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.
the total surface area of a prism or pyramid is the combined area of its lateral faces and its base s similarly the total surface area of a cylinder or cone is the combined area of its lateral surface and its base s the total surface area of a solid can also be thought of as the area of the solid s net examples given a bedroom in the shape of a rectangular prism the total surface area is the area of the four walls plus the area of the ceiling and the floor given a cylindrical soup can the total surface area is the area of the can s label plus the combined area of the top and bottom of the can
