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.
V of a circular slab = thickness of the slab multiplied by (pi multiplied by the radius2)
