One square yard is nine square feet, so 27 square feet is equivalent to 3 square yards. So 3 yards of concrete will cover 27 square feet.
It is about 166.67 cubic feet and you will need just over 6.17 cubic yards of concrete.

If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.

approx. 74 yards Sorry, Dabar, but I think you have not accounted for the conversion of cu. feet to cubic yards...my calculations are as follows...... 40 X 17 is equal to 680 cubic FEET of area. You take the 680 and divide by 27 to get the cu. YARDS of concrete. (25.1 cu. yds) Then because you only want the slab 4 inches thick, you multiply by .33 (or 8.25 cu. yards of concrete) Then you allow 10 % for waste or shortage....(make this about a yard...so, 8.25 and one for waste/shortage is equal to 9.25 cu. yards of Concrete for this project)
1000 square feet/9 = 111.1 square yards of concrete 6 inches thick. This is the same as 111.1/4.5 = 24.7 cubic yards of concrete.

For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.

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.
One square yard is nine square feet, so 27 square feet is equivalent to 3 square yards. So 3 yards of concrete will cover 27 square feet.
one (1) cubic yard of concrete four inches thick will cover 80 sq. feet. 85 yards x 81 = 6885 sq. feet.
