Using the perimeter of the base and the height you will compare and contrast the methods from the two examples to form the general formula for. The altitude or height of a prism is the perpendicular distance between the two bases. Looking at the rectangular prism template it is easy to see that the solid has six sides and each side is a rectangle.

Lets build our equation for surface area of a rectangular prism starting with our formula. This video illustrates how to use the formula for Lateral Area of a Rectangular Prism. You can think of the lateral surface area as the total surface area of the prism minus the two triangular areas at the top and bottom of the prism. In this tutorial youll see how to use the dimensions of a rectangular prism to find the lateral area.
