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.
Lateral surface area of rectangular prism = PH = 2(L + W)HWhere, 'L', 'W' and 'H' be the length, width and height of the prism. Surface Area of a Rectangular Prism is the measure of how much exposed area a prism has. Surface Area is expressed in square units.
