# Rectangular Prism - Definition with Examples

## What is a Rectangular Prism?

Rectangular Prism Definition: A rectangular prism is a 3-dimensional solid shape with 4 rectangular sides joined together at the edges, and forming two pairs of rectangular bases parallel to each other.

**Types of Rectangular Prisms **

Rectangular prisms are of two types:

**Right Rectangular Prism**: A rectangular prism whose sides are at right angles to the bases are known as right rectangular prism.

**Non-Right Rectangular Prism**: A rectangular prism whose sides are not at right angles to the bases are known as non-right rectangular prism.

**Rectangular Prism and its Net**

The net of the rectangular prism consists of two identical rectangular bases and 4 rectangular sides.

**Surface Area of a Rectangular Prism **

Consider a rectangular prism of length (l), height (h) and width (w).

Area of the orange face = 2 (width × length) = 2wl

Area of the blue face = 2 (length × height) = 2lh

Area of the green face = 2 (width × height) = 2wh

Surface area = Sum of all the area of its faces = 2wl + 2lh + 2wh = 2 (wl + lh + wh)

Surface area = 2 ( wl + il + wh ) |

**Volume of a rectangular prism **

Volume of a rectangular prism is simply obtained by multiplying all three dimensions. i.e. length (l), height (h) and width (w).

Volume = l X W X h = lwh |
