Volume and Surface Area of Regular Pentagonal Prism Calculator
What is a Regular Pentagonal Prism?
A regular pentagonal prism is defined as a three-dimensional figure bounded by two parallel pentagonal bases and five rectangular lateral faces. They are often called prisms because the shape of the figure is a triangle, which is maintained throughout the height.
Key Features of a Regular Pentagonal Prism
- Bases: Two regular concave pentagons that are congruent (all sides and angles equal).
- Lateral Faces: Five faces that are rectangles that connect the two bases and the edges of the bases.
- Height (h): The distance from one pentagonal base to the other in a direction perpendicular to the base planes.
- Edge Length (s): The size of each edge of the shape that makes the sides of the pentagonal base.
Calculating the Volume and Surface Area of a Regular Pentagonal Prism: Examples
1. Volume Calculation for a Regular Pentagonal Prism
Volume can be calculated for a regular pentagonal prism using the following formula:
V = A_b × h
Where:
- V is Volume of the pentagonal prism.
- A_b is the Area of the pentagonal base.
- h is the Height of the prism.
To determine the Area A_b of the pentagonal base, use the formula:
A_b = (5/4) × s² × cot(π/5)
Where:
- s equals Side length of the pentagon.
2. Finding Surface Area of a Regular Pentagonal Prism
The Area “A” of a perpendicular shaped pentagonal prism base is equal to:
A = 2 × A_b + A_l
Where:
- A_b is the area of one pentagonal base.
- A_l is the area of the five lateral rectangular faces.
The lateral surface area is calculated as:
A_l = 5 × (s × h)
Thus, the general formula for the surface area of a pentagonal prism is:
A = 2 × A_b + 5 × (s × h)

Frequently Asked Questions
1. What is a regular pentagonal prism?
A regular pentagonal prism is defined as a three-dimensional figure that has two parallel and congruent bases that are regular pentagons. Additionally, it has 5 rectangular lateral faces. It is a particular type of prism which has an increase in the height while a similar pentagonal cross-section is retained.
2. What steps should I follow to obtain the volume of a pentagonal prism?
The volume of a prism with a regular pentagonal base can be calculated using the following equation:
V = A_b × h
Where A_b is the volume of the pentagonal base and h is the height of the prism.
3. What method do I use to find the surface area of a normal pentagonal prism?
The surface area is defined as the total area of the two pentagonal bases in addition to that of the five vertical rectangular lateral sides.
A = 2 × A_b + 5 × (s × h)
4. What if I do not have the area of the base?
In instances where you have no information regarding the area of the base, it can be calculated as:
A_b = (5/4) s² cot(π/5)
All that is needed is to type in the side length s and the calculator will derive the base area automatically.
