There are 3 feet in a yard, so therefore 10 ft x 10 ft is 3.33 yd x 3.33 yd.
If the slab is the standard 4" deep, you will need at least 8.89 cubic yards.
4.074 cubic yards for every foot the slab is thick.
You can't express a volume of concrete in yards.
How many square yards in a 20x18 feet 3 inches thick
To calculate the volume of concrete needed for a 10' by 10' slab that is 6 inches deep, first convert the depth to feet: 6 inches is 0.5 feet. The volume in cubic feet is then calculated as 10' x 10' x 0.5' = 50 cubic feet. To convert cubic feet to cubic yards, divide by 27 (since there are 27 cubic feet in a cubic yard): 50 ÷ 27 ≈ 1.85 cubic yards of concrete is needed.
Assuming you need a slab 25 feet x 32 feet x 4" you would need 10 yards of concrete. 25 x 32 x .33 / 27 = 9.7 cubic yards
If the slab is the standard 4" deep, you will need at least 8.89 cubic yards.
how many yards of concrete will i need to do a 20 x20 x4 slab
37.03 yards
For a 4-inch depth you will need 7.41 cubic yards.
For a 4-inch thick slab, you will need at least 9.48 Cubic Yards.
A 40x60x6in slab requires 44.44 cubic yards of cement.
4.074 cubic yards for every foot the slab is thick.
3.95 cubic yards of cement are needed for a slab that size.
about 5 yards if your slab is 4" deep
1.19 Cubic Yards
To calculate the volume of a concrete slab, multiply the length, width, and depth. For a 10 x 12 x 4 slab, the volume is 10 feet × 12 feet × 4 feet = 480 cubic feet. Since concrete is typically sold by the cubic yard, convert cubic feet to cubic yards by dividing by 27. Therefore, you will need approximately 17.78 cubic yards of concrete for the slab.
