How to Calculate Volume Of Prism
Example: What is the volume of prism with no-of-sides = 3 units, side-size = 20 units and altitude = 23 units?
As;
volume of prism = no-of-sides*(side-size)2/(4*tan(180/no-of-sides))*altitude
By substituting the above given data in the previous function;
(i.e.) = 3*(20)2/(4*tan(180/3))*23
Answer is: units3.
