# Write a program to find the Area of the Rectangular Prism

Before writing the program of calculating the area of a rectangular prism in different programming languages, firstly we have to know about the rectangular prism and its area's formula.

### What is Rectangular Prism?

Rectangular Prism is a 3-D shape, which has six faces, 8 vertices, and 12 edges. This object is similar to cuboids. All the faces of this shape are rectangle.

### Area of Rectangular Prism

To calculate the surface area of rectangular prism, first we have to use the following formula:
