Measure the distance from the back of the mounting lip to the rear of the magnet (edge) Then use this formula For "X" plug in the distance of the measurement you took in inches. 4*0.33*3.14"X" ^3*.05*.06

Answer will be in cubic ft.

That will give you a good estimate, but is not always 100% accurate.
