About the Rectangular Prism Calculator

The rectangular prism calculator is a convenient online tool that computes the geometric parameters of a rectangular prism. From the length, width, and height you enter, it automatically calculates the volume, surface area, and the three different face areas.

How to Use the Rectangular Prism Calculator?

1. Enter the dimensions: type the length, width, and height values in the input boxes. All inputs should be positive numbers (integers or decimals).
2. Choose the unit: select a suitable unit from the "Unit" dropdown: millimeters (mm), centimeters (cm), decimeters (dm), or meters (m).

4. View the results: the results appear in the boxes below:

• Volume: the total volume of the prism (length × width × height).
• Surface area: the total surface area of the prism (sum of the areas of all faces).
• A area: the area of the length × width face.
• B area: the area of the length × height face.
• C area: the area of the width × height face.
