The Rectangular Prism Calculator is a useful online tool that helps you calculate key properties of a rectangular prism. With this calculator, you can find the volume, surface area, lateral surface area, face diagonal, and space diagonal just by entering the length, width, and height. It is ideal for students, teachers, builders, and anyone who needs quick geometry help.

What Is a Rectangular Prism?

A rectangular prism is a 3D shape with six faces, all of which are rectangles. It has three dimensions: length, width, and height. Every face meets at right angles, making it a type of cuboid. Boxes, bricks, and books are common examples of rectangular prisms in real life.

Formulas Used in the Calculator

  • Volume: Length × Width × Height
  • Surface Area: 2 × (Length × Width + Length × Height + Width × Height)
  • Lateral Surface Area: 2 × Height × (Length + Width)
  • Face Diagonal: √(Length² + Width²)
  • Space Diagonal: √(Length² + Width² + Height²)

How to Use the Rectangular Prism Calculator

  1. Enter the length of the prism.
  2. Enter the width of the prism.
  3. Enter the height of the prism.
  4. The calculator will automatically show all key results: volume, surface area, and diagonals.

You can use any unit (cm, inches, meters, etc.), but make sure all inputs are in the same unit to keep the output accurate.
