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!

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.

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.

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.
