Rectangular Prism Volume and Surface Area Calculator

Calculate the volume and surface area of a rectangular prism with our easy-to-use calculator. Learn about rectangular prism formulas, real-world applications, and explore interactive examples.

A rectangular prism (or cuboid) is a three-dimensional shape with six rectangular faces. Our calculator helps you determine both the volume and surface area using length, width, and height. Perfect for calculating storage space, material requirements, and more.

Formula

Volume = l × w × h
Surface Area = 2(lw + lh + wh)

Where:

  • l:length of the rectangular prism
  • w:width of the rectangular prism
  • h:height of the rectangular prism

Frequently Asked Questions

What is a rectangular prism?

A rectangular prism is a three-dimensional shape with six rectangular faces. Each face meets at right angles with its adjacent faces, creating a box-like shape.

How do you find the volume of a rectangular prism?

To find the volume of a rectangular prism, multiply its length by its width by its height: V = l × w × h.

What is the surface area of a rectangular prism?

The surface area of a rectangular prism is the sum of the areas of all six faces. The formula is: SA = 2(lw + lh + wh), where l is length, w is width, and h is height.
