Hopefully I'm understanding this question correctly. I assume you mean a heating or air duct where, if round, is like a cylinder. The volume of a cylinder is equal to (pi)r2h, where pi = 3.142; r = radius; h = height. To understand why this is, picture a round duct or any cylinder. The base is a circle. The area of a circle is equal to (pi)r2. If you stand a bunch of circles on top of each other (equal to the height) the object now looks like a cylinder and the area of all those circles will equal the volume of the cylinder. To answer your question, you calculate the volume of a round duct by figuring out the radius of the base circle and the height of the object and then use the formula (pi)r2h. The answer that you get will be in cubic units.
