The volume of a pentagonal prism is the room occupied by it. A prism is a three-dimensional shape having actually identical bases, flat rectangular next faces, and the very same cross-section all along its length. Prisms space classified into different varieties and named as per the form of your base. A pentagonal prism together the name says is a three-dimensional heavy that has actually two pentagonal bases: bottom and top. The sides of a pentagonal prism are rectangular in shape. Over there is a formula to find the volume of a pentagonal prism. Let's explore and also learn in detail!

What is Volume that Pentagonal Prism?

The volume the the pentagonal prism is characterized as the capacity of the pentagonal prism. In geometry, a pentagonal prism is a three-dimensional form with two pentagonal bases and five rectangular faces. So, a pentagonal prism has actually a total of 7 faces(out of i beg your pardon 2 encounters are pentagonal in shape), 15 edges, and also 10 vertices. By definition, there are 2 pentagonal bases that room congruent to each other. It has actually 5 lateral deals with of rectangle shape, vice versa, its bottom and also top are of pentagon shape. The volume the the pentagonal prism is measured in cubic units such together cm3, m3, in3, etc.

Volume that Pentagonal Prism Formula

We will watch the formulas to calculation the quantities of different species of pentagonal prisms. The volume of any type of prism is acquired by multiply its basic area by its height. I.e., the volume the a prism = base area × height. We will use this formula to calculate the volume the a pentagonal prism as well. We know that the base of a pentagonal prism is a pentagon. By using the over formula, the volume the a pentagonal prism = area of basic × height.

The volume of a pentagonal prism = area of basic × height

The volume of a pentagonal prism determines the capacity of the prism. Together per the general formula that the volume that a prism, the is, volume = area of base × height. The area of basic = 1/2 × Perimeter × Apothem sq units, wherein perimeter = 5b. Thus, the formula because that the volume the a pentagonal prism is: Volume = (5/2 × abh) cubic devices where,

b = Base size of the pentagonal prismh = elevation of the pentagonal prism


Since the third dimension of measurements has come right into the picture, thus the unit will certainly be cubic units like these cubic centimeters. There space three species of pentagonal prism - regular pentagonal prisms, right pentagonal prisms, and oblique pentagonal prisms.


In the instance of a constant pentagonal prism, both the pentagonal sides space of same length and also the 5 rectangular sides v bases being perpendicular to every other.In the instance of a ideal pentagonal prism, the bases space perpendicular to every other.

How To calculate the Volume of Pentagonal Prism?

Here are the measures to calculate the volume of a pentagonal prism. We must be sure that all measurements are of the exact same units. Describe the example given listed below followed by the steps.

Step 1: recognize the apothem length and also base length and find its area using a suitable formula(base area= 5/2ab).Step 2: identify the provided height the the prism (It have to be the elevation of the full prism).Step 3: Find the product of its base area and also the height to discover the volume.

Example: calculation the volume of the pentagonal prism if the apothem length "a" that a pentagonal prism is 5 feet, the base length "b" is 4 feet, and the height "h" is 6 feet.

Solution: Given the a = 5 feet, b = 4 feet and also h = 6 feet. The volume that the pentagonal prism is acquired using the formula V = 5/2 × abh. The measures to identify the volume of the pentagonal prism are:

Step 1: The area the the base of the pentagonal prism is uncovered using the formula, 5/2ab = 5/2 × 5 × 4 = 50 square feet.Step 2: The height of the prism is 6 ft.Step 3: The volume that the pentagonal prism = basic area × height = 50 × 6 = 300 cubic feet.

Thus, the volume that the pentagonal prism is 300 cubic feet.

Example 2: Ron has to determine the capacity of a container that is pentagonal prism-shaped. So he made decision to to fill it through water up to the brim. Calculate the volume the the container i beg your pardon has, apothem length, a = 20 feet, basic length, b = 12 feet, and height, h = 10 feet

Solution: To understand the capacity of the container, Ron needs to find the volume that the container. Provided that a = 20 feet, b = 12 feet and h = 10 feet. The volume the the pentagonal prism-shaped container is:

V = 5/2 × abh⇒ V = 5/2 × 20 × 12 × 10 = 6000 cubic feet.
