## How to Calculate Area Of Prism

*Example: What is the area of prism with no-of-sides = 4 units, side-size = 15 units and altitude = 29 units?*

As;

area of prism = 2*no-of-sides*(side-size)^{2}/(4*tan(180/no-of-sides))+no-of-sides*side-size*altitude

By substituting the above given data in the previous function;

(i.e.) = 2*4*(15)^{2}/(4*tan(180/4))+4*15*29

Answer is: units^{2}.
