1 cubic yard covers 324 square feet per inch of thickness, divide 324 by thickness in inches to get coverage, i.e. 4 inches thick would cover 324/4=81 square feet, 36 inches thick would cover (you guessed it) 9 square feet.
A 60-pound bag of concrete mix typically yields about 0.45 cubic feet of concrete. To convert this to square feet, you need to know the thickness of the slab you plan to pour. For example, if you're pouring a 4-inch thick slab, the 60-pound bag would cover approximately 13.5 square feet.
To calculate the amount of concrete needed for a 12 x 15 slab, first find the area in square feet: 12 x 15 = 180 square feet. Then, convert square feet to cubic yards by multiplying the area by the desired thickness (in feet) and then dividing by 27 (since there are 27 cubic feet in a cubic yard). For a standard 4-inch thick slab, the calculation would be 180 x (4/12) / 27, resulting in approximately 2.67 cubic yards of concrete needed.
For a 4-inch depth you will need 7.41 cubic yards.
2.25 square feet.
1000 square feet/9 = 111.1 square yards of concrete 6 inches thick. This is the same as 111.1/4.5 = 24.7 cubic yards of concrete.
A yard of concrete is a cubic yard and cannot be converted directly to square feet of coverage. You must first determine the depth or thickness that the concrete will be. For instance, since 1 cubic yard equals 27 cubic feet, a 1 foot thick layer of concrete will cover 9 square yards of area. A 4 inch (1/3 foot) thick layer would cover 27 square feet of area.
For a 4-inch thick slab, you will need at least 9.48 Cubic Yards.

On average, concrete weighs about 12.5 pounds per square foot per inch thick. This can vary based on the type and density of the concrete mix.
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
