How do you calculate volume using prismoidal formula with an example?

Answer 1

Obtaining a volume using the prismoidal formula requires you 4 data:

H - the depth of the solid

A1 & A2 - the area at ends of the solid

Am - the area at mid-depth of the solid (you may draw the plan view of the solid with the top and bottom faces, connect the joints which offset each other, obtain the center of each line drawn such way and connect the dots. with this, you may be able to obtain your Am)

After collecting the required data, apply the following formula:

V = H / 6 * (A1 + 4*Am + A2)

Hope this answers your question.
