Yards are for measuring length not volume. Cubic yards required will be as follows: 1 cubic yard = 3 feet x 3 feet x 3 feet = 27 cubic feet Your concrete pad is 30ft x 40ft x 0.3333ft (4 inches assumed) = 400 cubic feet 400 divided by 27 = 14.8148 cubic yards required
A cubic yard = 3' x 3' x 3' = 27 cubic feet = 3888 cubic inches
about 432 cubic inches
147 cubic feet of cement are required.
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.
Essentially, you need three and a third cubic yards of concrete to replace that quantity to those measurements - so if the cost of a cubic yard of concrete is 30, multiply it by 3.333 and you get 100
Not square yards, but Approx. 5.24 cubic yards 54'2" = 650" x 7'10" = 94" x 4" = 4" = 244,400 cubic inches / 46,656 cubic inches = 1 cubic yard (36" x 36" x 36")= 5.24 cubic yards
