Pentagonal Prism Definition:
     The pentagonal prism is a prism having two pentagonal bases and five rectangular sides.

Pentagonal Prism Formula :
Area of Base(A) = ½ * a * 5 * s
Perimeter of Base(P) = 5s
Surface Area of Prism = 5as + 5sh = 5as + Ph
Volume of Prism = (5/2)ash = Ah
where
        a = apothem length, s = side, h = height.

Pentagonal Prism Example :
Case 1: Find the surface area and volume of a pentagonal prism with the given apothem length 2, side 3 and height 4.

  Step 1: Find the area of the base.
            Area of the base(A) = ½ * a * 5 * s = 0.5 * 2 * 5 * 3 = 15.

  Step 2: Find the perimeter of the base.
            Perimeter of the base(P) = 5s = 5 * 3 = 15.

  Step 3: Find the surface area of prism.
            Surface Area of Prism = 5as + Ph = (5 * 2 * 3) + (15 * 4) = 30 + 60 = 90.

  Step 4: Find the volume of prism.
            Volume of Prism = Ah = 15 * 4 = 60.

The above example will clearly illustrates how to calculate the Volume, Surface Area, Perimeter of a Pentagonal Prism manually.
