# Volume of a Rectangular Prism Calculator

The volume of a rectangular prism calculator can help you obtain the volume of a rectangular prism from its width, length, and height!

We paired this calculator with a short text covering:

- What a rectangular prism is;
- Volume of a rectangular prism formula,
- How to find the volume of a rectangular prism; and
- Some use-cases for this calculator.

Let's dive right in!

## What is a rectangular prism?

A rectangular prism is any three-dimensional prism where all of its faces (top, bottom, and sides) are rectangles. This simple definition instantly shows a few properties of rectangular prisms:

- Opposite faces of a rectangular prism are
**identical**. - They have:
**8 vertices**;**12 sides**; and**6 sides**.

- It has three dimensions:
**Length**;**Width**; and**Height**.

Some authors use a slightly different definition and distinguish between two types of rectangular prisms:

**Right rectangular prism**, where its faces are perpendicular to its bases; and**Oblique rectangular prism**, where its faces are not perpendicular to its bases.

We will use the **right rectangular prism** definition in this volume of a rectangular prism calculator.

## How to find the volume of a rectangular prism

We can easily find the volume of a rectangular prism by multiplying the length of its dimensions together. According to the volume of a rectangular prism formula, we have:

where:

- $l$ is its
**length**; - $w$ is its
**width**; and - $h$ is its
**height**.

🙋 You can input these dimensions in any length unit with this volume of a rectangular prism calculator! You can also manually convert the units using our length converter.
