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.
Volume of a Triangular Prism Volume= 0.5(area of the base)(distance between 2 faces)   Answer: Volume of a triangular prism = (area of the base) (perpendicular distanâ¦ce between the 2 bases of the prism) Since it is a triangular prism, the base of the prism is triangle in shape.
