Rectangular Prism Calculator

Enter the dimensions of the rectangular prism to calculate its volume and surface area.

For example, if length=10, width=5, and height=8: $$ \text{Volume} = 10 \times 5 \times 8,\quad \text{Surface Area} = 2(10\times5 + 10\times8 + 5\times8). $$

Step 1: Enter Dimensions

Enter the length of the prism

Enter the width of the prism

Enter the height of the prism

Formulas used: $$ \text{Volume} = L \times W \times H, \quad \text{Surface Area} = 2(LW + LH + WH). $$

Understanding Rectangular Prisms

Rectangular Prism: A Complete Guide

What is a Rectangular Prism?

A rectangular prism is a three-dimensional geometric shape with six rectangular faces. Each pair of opposite faces is identical, and all its internal angles are right angles. It is also commonly referred to as a cuboid.

Properties of a Rectangular Prism

  • It has 6 faces, 12 edges, and 8 vertices.
  • Opposite faces are equal and parallel.
  • All internal angles are 90 degrees.

How to Calculate the Volume

The volume of a rectangular prism represents the amount of space it occupies. It is calculated using the formula:

Volume = Length × Width × Height

For example, if the length is 5 units, the width is 3 units, and the height is 4 units, the volume is:

Volume = 5 × 3 × 4 = 60 cubic units

How to Calculate the Surface Area

The surface area is the total area of all six faces of the prism. The formula is:

Surface Area = 2 × (Length × Width + Length × Height + Width × Height)

For example, if the dimensions are the same as above:

Surface Area = 2 × (5 × 3 + 5 × 4 + 3 × 4) = 94 square units

Common Uses of Rectangular Prisms

  • Storage Solutions: Used in the design of boxes, containers, and cabinets.
  • Construction: Bricks and beams often take the shape of rectangular prisms.
  • Mathematics and Education: Helps in learning geometry concepts.
  • 3D Modeling: Frequently used in computer-aided design (CAD) applications.
