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.

How do you calculate the volume of concrete in a circular slab?
V of a circular slab = thickness of the slab multiplied by (pi multiplied by the radius2)
How do you calculate the area of a rectangular slab?
Multiply the length by the breadth. eg if slab is 2 ft by 3 ft then area of slab = 6 sq feet
How many yards of concrete for slab that is 20'x60'x4''?
14.8 cubic yards will work but round to 15 to be sure.
How many yards of concretein a slab 20'x16x?
For a standard 4-inch thick slab, this area needs at least 3.95 cubic yards.
How much concrete is needed for a slab 9 square feet and 4 inches thick?
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.
