The best part about the internet is I can see this now and in a few years when I am doing this at a friends house instead of having to find a place to put this information that I KNOW I will find then.
A more accurate formula is Width in feet X Length in Feet X depth in inches / 12 (or in your first example is 3x20x4/12) which gives you 20 cubic feet of concrete. 19.8 is wrong, which is due to the fact that .33 is not accurately 1/3, and the larger the other numbers, the more your answer is going to be off.
Good point and this problem can easily be soved by using .3333 two represent one fourth instead of .33. Now I have to admit when I made a mistake and this is actually something I didn't realize, until I did some math and found out that this individual was correct. On our small sidewalk it might not be that big of a deal, but on a 100 x 100' concrete slab 4 inches thick we would be off more than a cubic yard. Thanks for sharing and comments like yours are always sincerely appreciated.
There are too many variables in a variety of different types of jobs. For example is going to be easier to figure out how much to charge for building a 2' x 2' sidewalk than a 40 foot square building foundation.

You're welcome and your dad sounds like a smart guy.

Very Helpful thanks!
You're welcome!
Does anybodys mind go blank as soon as numbers are thrown about? If there was no decimal I’d probably be ok
