1.7 cubic yards of concrete Dondeb...that is an incorrect answer...Lets do this in steps.... 1. 80 X 30 = 240 Surface feet. Divide by .50 because you want it 6 inches deep. 2. 240 divided by .50 = 120 3. 120 is the total square feet of material needed. 4. Divide by 27 as there are 27 cubic feet to a cubic yard....(120 divided by 27) 5. 4.4 cubic yards of concrete are needed, that is if you don't take into account up to 10% for loss or shortage. If this were my project I would order 5 cubic yards.
2.2 Yards
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
about 5 yards if your slab is 4" deep

If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
You'll need 1.23 Cubic Yards.
It is about 166.67 cubic feet and you will need just over 6.17 cubic yards of concrete.

12.30 cubic yards
That depends on how DEEP you want the concrete !
That's just about 3.9 cubic yards for every 6 inches deep.
You will need 0.56 cubic yards of concrete.
