Multiply length times width. IF your driveway was 1 foot thick that would be the number of cubic feet of concrete. HOWEVER- it is only 4 inches thick. That is .33 ft (one third of a foot). So take your answer you got from multiplying LxW, and divide by 3. That will be the number of cubic feet of the driveway's volume.

It depends on the thickness and the density. One ton should be about 15 cubic feet when compacted, so it would cover 30 square feet 6 inches thick or 45.
