# Surface Area of a Heptagonal Prism Calculator

This online calculator is used to find the surface area of the heptagonal prism. A prism with square sides and heptagons as its base is the heptagonal prism. The surface area (SA) of the prism is the total area that is occupied by the heptagonal prism surface. Enter the value of the base edge and height to find the SA.

#### Formula:

A = 7 * a * h + ( 7 / 2 ) * a2 * cot( 180° / 7 ) Where, A = Surface Area a = Base Edge h = Height

#### Example

If the base edge and height of the heptagonal prism is 20 m and 100 m

Surface Area = 7 * 20 * 100 + ( 7 / 2 ) * 202 * cot( 180Â° / 7 ) =16908.82 m2
