Depends on how thick the slab is, but 4" thick (.33 or 1/3 of a foot thick) would be typical. So multiply 10 x 10 = 100 square feet of area times .33(thickness in feet) equals 33 cubic feet. A 90 lb. bag contains about .66(two thirds) of a cubic foot of concrete, so you would need about 1 1/2 bags per cubic foot or 50 bags for 10'x10'x4"

To calculate the number of concrete bags needed for a 10x10x2 foot slab, first find the volume in cubic feet: 10 x 10 x 2 = 200 cubic feet. A standard 80-pound bag of concrete typically covers about 0.6 cubic feet. Therefore, you would need approximately 334 bags (200 ÷ 0.6 ≈ 333.33) of concrete to fill that volume.
To determine how many 80-pound bags of concrete are needed to fill an 8-foot by 8-foot by 5-inch thick slab, first calculate the volume of the slab. The volume is 8 ft x 8 ft x (5/12) ft = 26.67 cubic feet. An 80-pound bag of concrete typically yields about 0.6 cubic feet, so you would need approximately 45 bags (26.67 cubic feet ÷ 0.6 cubic feet per bag).
9.33 bags. Concrete mix is usually is 60 or 80 lb bags, so check the labels.

Each 60 pounds bag of ready mix concrete will make .45 cubic foot of concrete. There are 27 cubic feet in a cubic yard. You will need 60 bags of 60 pound premixed concrete to make 1 cubic yard.
What size bags of concrete and how big are the bricks? Makes a difference.
