HxWxD then take that divide by 1728 :)

12x12x12 = 1728/1728 = 1cf ;)

(l)(w)(h)=airspace if you use inches divide your answer by 1728 to get cubic feet

All he said was if you are measuring in inches divide by 1728 to get cf.

Other measurements convert them to inches then you can divide to get 1728.

Make sure you account for wood thickness, so use internal dimensions.

I was gonna ask where the 1728 came from, but it seems that 1728 cubic inches is equal to a cubic foot?

Yes 1728 in^3 = 1 ft^3 because..
there are 12" in a foot obviously, and so 12" * 12" * 12" = 1' * 1' * 1' = 1'^3
