0.246914 cu. yards (6.666667 cu. ft ) of concrete is needed.
To my knowledge, concrete is measured in cubic yards. you would convert your measurements to yards 2000 sq ft is about 222.22 sq yards 4 inches is about 0.11 yards multiply to get volume, about 24.7 cu yards
For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.
5 (Five) Close enough.
The term "yards" of concrete means 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.
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)
You need to specify the slab's width and the length as well.
9x12 feet at 4 inches deep: 1.3 cubic yards.
