To calculate the number of yards of concrete needed for a 30 x 40 slab, first determine the volume in cubic feet. The volume is calculated as length × width × thickness. Assuming a standard thickness of 4 inches (1/3 feet), the volume is 30 × 40 × (1/3) = 400 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 400 by 27, resulting in approximately 14.81 cubic yards of concrete needed for the slab.

How many yards of concrete in a 20ft by 30 ft slab 5 inches thick?
9.3 cubic yards of cement is required for this slab.
How many yards of concrete needed for 24' X 30' X 6 slab?
To calculate the amount of concrete needed for a slab, you can use the formula: volume = length × width × depth. For a 24' x 30' slab with a depth of 6 inches (0.5 feet), the volume is 24 × 30 × 0.5 = 360 cubic feet. Since there are 27 cubic feet in a cubic yard, you would divide 360 by 27, resulting in approximately 13.33 cubic yards of concrete needed for the slab.

3.70 yards and you will order 4 yards to have enough. (30 x 10 x 1/3) = 100 cubic feet Divided by 27 = 3.704 cubic yards
How many yards of concrete in a 24 x 30 slab?
Assuming a thickness of four inches and allowing about 5% waste, you would need 9.33 cubic yards or about 419 80lb bags.
How much concrete 30'x40'?
To calculate the amount of concrete needed for a 30'x40' slab, you first need to determine the thickness of the slab. For example, if the slab is 4 inches thick, convert the dimensions to feet (30' x 40' x 0.33' for 4 inches). Then, multiply the length, width, and thickness: 30 x 40 x 0.33 = 396 cubic feet. To convert cubic feet to cubic yards, divide by 27, resulting in approximately 14.67 cubic yards of concrete needed.

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 for a 28 by 30 slab?
To calculate the amount of concrete needed for a 28 by 30 slab, first determine the slab's thickness. For example, if the slab is 4 inches thick (0.33 feet), the volume in cubic feet is 28 ft × 30 ft × 0.33 ft = 277.2 cubic feet. Since there are 27 cubic feet in a cubic yard, you would need approximately 10.3 cubic yards of concrete for the slab. Always consider ordering a little extra to account for spillage and variations in thickness.
How many yards of concrete fo a slab 30x30x4 thick?
If the units are 30 ft x 30 ft x 4 inches, then you have 30 x 30 x 0.33 ft = 300 cubic feet300 cubic ft/27 cu yds/cu ft = 11.1 cubic yards
How many yards of concrete will a 20 by 30 slab need?
To calculate the amount of concrete needed for a 20 by 30 slab, first determine the area in square feet: 20 feet × 30 feet = 600 square feet. If the slab is, for example, 4 inches thick, convert the thickness to feet (4 inches ÷ 12 inches/foot = 0.33 feet). The volume in cubic feet is then 600 square feet × 0.33 feet = 198 cubic feet. Finally, convert cubic feet to cubic yards by dividing by 27 (since there are 27 cubic feet in a cubic yard): 198 ÷ 27 ≈ 7.33 cubic yards of concrete needed.
How many yards of cement does it take for a 3 inch slab 30 feet by 10 feet?
About 3.
How many yards of concrete it will take to pour a concrete slab that is 30ft x 40ft x 4 inches thick with footers?
To calculate the volume of concrete needed for a slab that is 30 feet by 40 feet and 4 inches thick, first convert the thickness to feet: 4 inches is 1/3 foot. The volume in cubic feet is 30 x 40 x (1/3) = 400 cubic feet. To convert cubic feet to cubic yards, divide by 27 (since there are 27 cubic feet in a cubic yard): 400 ÷ 27 ≈ 14.81 cubic yards. If footers are included, you would need to add their volume based on their dimensions to this total.
