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:

V=l×w×hV= l\times w\times h

where:

  • ll is its length;
  • ww is its width; and
  • hh 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.

Using the volume of a rectangular prism calculator

There are many cases where this tool can prove itself useful, such as:

  • Comparing two different suitcases to find the largest between them to take on a trip 🧳;
  • Finding the amount of water needed to fill a fish tank of known dimensions 🐠;
  • Calculating the cost to ship a box with a logistics company 📦;
  • Many more.

If you want to find the volume of other three-dimensional figures, you can take a look at our sphere volume calculator and cylinder volume calculator.
