The pipe is a cylinder.
Volume is generally length * width * height, but the pipe is not square, it has a circle for a cross-section. So instead of width * height (as in a square) you need to use the formula for the area of a circle: pi * radius-squared.
You also need to put the pipe diameter (inches) and the pipe length (feet) in the same dimensions (inches for both, or feet for both).
The volume in cubic inches is: pi (3.1415...) times the radius (radius is half the diameter 3") times the radius times the length in inches (20 feet * 12 inches/foot)
Or in cubic feet
pi times the radius (in feet 3 inches is 1/4 foot, then half of that) times the radius times 20 feet

diameter = 3 in
length = 240 in
volume = pi*d^2 / 4 * 240
volume = 1696.464 cubic inches
