14.8 cubic yards will work but round to 15 to be sure.
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 a standard 4-inch thick slab, this area needs at least 3.95 cubic yards.
The cross-sectional area of a concrete slab is the total area of the slab when viewed perpendicular to its length and width. To calculate the cross-sectional area, you multiply the length of the slab by the width of the slab. This measurement is crucial for determining the amount of concrete needed for a project and for ensuring the structural integrity of the slab.
A 9x9 foot slab 4 inches thick requires a minimum of 1 cubic yard. If you go to 6 inches thick you will need 1.5 cubic yards.
To calculate the volume of concrete in cubic yards for a slab that is 40 feet by 60 feet and 6 inches thick, first convert the dimensions to feet. The thickness in feet is 0.5 feet. The volume in cubic feet is 40 x 60 x 0.5 = 1200 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 1200 by 27, resulting in approximately 44.44 cubic yards of concrete.
