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 surface area of a prism is the sum of the areas of all its faces. A two-dimensional representation of a solid is called a net . Lateral Face. Base. Section 6.2 Surface Areas of Prisms 257. Work with a partner. Find the surface area of the solid shown by the net. Copy the net, cut it out, and fold it to form a solid.
