# Surface area of a rectangular prism

The surface area of a rectangular prism is is the area of the six rectangles that cover it.
If we break the rectangular prism into its parts we are going to have 2 bases and 4 lateral faces (rectangles) which make up the lateal area. It is pretty easy to calculate their areas and then add them up.

What is the surface area? A rectangular prism has 3 pairs of identical faces. Each face is a rectangle.

Find the area of the faces in each pair. Now add the areas of the 6 faces.

 Surface area = 24 + 24 + 54 + 54 + 36 + 36 = 228

The surface area of the rectangular prism is 228 square centimeters What is the surface area when a=1, b=7 and c=7?
