The area of a 2 by 2 inch square is 4 square inches. The formula is length times width. Like 4 inch by 6 inch. 4 times 6 equals 24 square inches
roughly 240 square feet. Formula for figuring yardage is: (Width X Length X thickness)/27= cubic yardage of concrete. Just reverse the formula to solve for Width X Length or Square Feet. CY X 27 divided by thickness = square footage
It depends on the thickness of slab. A yard of cement contains 9 cubic feet. Thus, it would cover 9 square feet if the slab was 1 foot thick. For a 4 inch thick slab, it would cover 3 times as much area, or 27 square feet.
18 bags (80 pounds) of quikrete for a 4 inch thick slab.
2x2
1.25 cubic yards for a 4-inch slab. 2 cubic yards (1.85) for a 6-inch slab.
At least 3 cubic yards for a 4-inch slab. You'll need 4.75 cubic yards for a 6-inch slab.
The answer will depend on 4 inch slab of what material!
80% of 1 inch is 0.8 inches or 4/5 of an inch.
For a 4-inch thick slab you will need at least 1.2 cubic yards.
1.5 cubic yards of cement are needed for an 11' x 11' x 4" slab.

For a standard 4-inch thick slab, this area needs at least 3.95 cubic yards.
