To determine how many bags of concrete are needed for a slab measuring feet x feet x 4 inches, first convert the dimensions to cubic feet. A 4-inch thickness is equivalent to 0.33 feet, so the volume is calculated as length x width x 0.33. Then, divide the total cubic feet by the volume of a standard bag of concrete (usually 0.5 cubic feet). This will give you the number of bags required.
You need to specify the slab's width and the length as well.

How deep? Are you talking about dry mix weight or finished weight? Concrete weighs 150 pounds per cubic foot. So if you have a 6" slab, that's 150# for 2 square feet. For a 4" slab, the same amount will cover 3 square feet. For a 3" slab, 4 square feet. Concrete mix is commonly sold in 80 pound bags. The finished weight is the mix plus the water that gets chemically bound to it. There's a guide on the bag telling how many bags you need for a given area and thickness.
4.074 cubic yards for every foot the slab is thick.

18 bags (80 pounds) of quikrete for a 4 inch thick slab.
To determine how many bags of concrete you need for a 10 x 10 slab, first calculate the volume: a 4-inch thick slab is 10 x 10 x (4/12) = 33.3 cubic feet. A typical 80-pound bag of concrete covers about 0.6 cubic feet. Dividing 33.3 by 0.6 means you would need approximately 56 bags of concrete for that size slab.
