## How to Calculate Area Of Prism

### Example: What is the area of prism with no-of-sides = 3 units, side-size = 19 units and altitude = 24 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*3*(19)2/(4*tan(180/3))+3*19*24

### Practice Question: Calculate area of prism for the following problems:
