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.
