I'll assume you are talking a slab 40' x 50'. if that is the case you would have to supply a thickness for an accurate answer. Also, whether or not you have chainwalls. With more information you can get a much closer answer. if it's a flat pour with 4" thickness the answer is appx 25 yards.

How many yards of concrete will you need for a 3000 sq ft house slab?
40 yards.
How many yards of concrete for 24' x 40' 4 slab?
Volume = 11.85 Cubic Yards.
How many yards of concrete do you need for a slab that is 40x40x3in?
40" x 40" x 3" requires 0.1 cubic yards of cement. If you mean 40 x 40 feet, you will need 14.81 cubic yards of cement.
How many yards of concrete do you need for slab that is 40'x40'x6?
40 x 40 x 1/2 = 800 cubic feet. Divide 800 by 27 (27 cubic feet per yard) = approximately 29.6 yards.. round that up to 30 cubic yards of concrete.
How much concrete is needed for a 40 X 44 X 4 slab?
22 cubic yards
How many yards of concrete in a 40x40x6 slab?
A 40'x40'x6" slab requires 29.63 cubic yards of cement.

How many yards of cement needed for a slab that's 40'x40'x3?
14.81 cubic yards.
12 x 40 x 4 how many yards concrete?
you multiply 12 x 40 x .333 and then divide it by 27 which will give you 5.92 or 6 yards of concrete
How many yards of concrete do you need for a project 40 by 17 by 4 inches?
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)
How many yards of concrete do you need for my project 40 feet by 3 feet by 6 inches deep'?
2.2 Yards
How do you find how much concrete you need?
For slabs: ((H * W * D) / 27) *1.10 For fenceposts: one bag per post. An example for a slab: We are building a maintenance shop for big trucks. It will be 40 feet long, 50 feet wide and the slab will be six inches thick. So...40 x 50 is 2,000 square feet. Multiply that by 0.5 feet (a 3" slab is 0.25 feet, and a 4" slab is 0.33 feet) to get 1,000 cubic feet. Divide by 27 (the number of cubic feet in a cubic yard) to get 37.0370... cubic yards. Adding 10 percent (this is an industry standard) gives you 40.7407...cubic yards. This is a tricky one...concrete trucks hold either 6 or 11 yards of concrete and you get a full one when you order concrete, so you'll get either 42 yards (seven truckloads) or 44 (four loads).
How many yards of cement needed for a 40 x 60 slab at 8 inches thick?
8 inches = 2/3 foot27 cubic feet = 1 cubic yardVolume of your slab = 40' x 60' x 2/3 = 1,600 cubic feet = 59.26 cubic yards. (rounded)
