# What Is The Volume Of The Prism Given Below

In geometry, a prism is a solid figure with two parallel and congruent polygonal bases that are connected by lateral faces. The volume of a prism is a measure of the space occupied by the prism. It is calculated by multiplying the area of the base by the height of the prism. In this article, we will discuss how to calculate the volume of a prism given the dimensions of a specific prism.

## Prism Definition and Formulas

A prism is a polyhedron with two congruent and parallel polygonal bases. The lateral faces of a prism are parallelograms, and the height of the prism is the perpendicular distance between the two bases. The volume of a prism can be calculated using different formulas based on the shape of the base and the dimensions of the prism.

• Volume of a Rectangular Prism: The volume of a rectangular prism can be calculated using the formula V = lwh, where l is the length, w is the width, and h is the height of the prism.
• Volume of a Triangular Prism: The volume of a triangular prism can be calculated using the formula V = 1/2 * b * h * H, where b is the base of the triangle, h is the height of the triangle, and H is the height of the prism.
• Volume of a Pentagonal Prism: The volume of a pentagonal prism can be calculated using the formula V = 5/2 * apothem * base * height, where apothem is the distance from the center of the base to the midpoint of a side.

## Given Prism Dimensions

Let’s consider a specific example to illustrate how to calculate the volume of a prism given its dimensions. Suppose we have a rectangular prism with the following dimensions:

• Length (l): 10 units
• Width (w): 5 units
• Height (h): 3 units

## Calculating the Volume of the Prism

Now that we have the dimensions of the rectangular prism, we can calculate its volume using the formula V = lwh. Substituting the given values into the formula, we get:

Volume = 10 * 5 * 3 = 150 cubic units

Therefore, the volume of the rectangular prism with the given dimensions is 150 cubic units.

## Conclusion

In conclusion, the volume of a prism is a measure of the space occupied by the prism and is calculated by multiplying the area of the base by the height of the prism. Different formulas are used to calculate the volume of prisms with different base shapes. By knowing the dimensions of the prism, one can easily calculate its volume and determine the amount of space it occupies. Understanding the concept of volume in prisms is essential in various fields such as architecture, engineering, and mathematics.
