about 60 60lb bags
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.
One cubic yard is equivalent to 27 cubic feet. A 60-pound bag of Quikrete typically yields about 0.45 cubic feet of concrete. Therefore, to fill one cubic yard, you would need approximately 60 bags of 60-pound Quikrete bags (27 cubic feet ÷ 0.45 cubic feet per bag = 60 bags).
There is 0.45 cubic feet in a 60-lb bag, so you need 60 bags. If you go to 80-lb bags, there's 0.60 cubic feet and you need 45 bags.
80# bags are 0.6 cubic feet and it takes 41 to make a cubic yard. In that case, 60# bags must be 0.45 cubic feet and it would take 55 to make a cubic yard.
You will get not 2.3 cu ft you will probably need at least 50 to 60 bags to make cubic yard..

If your talking about 4'x4'x4" thick it will take about 12 bags. Most 60# bags will do .45 cubic feet and that slab would be about 5.3 cubic feet wich equals 11.77 bags.. Mike
To determine how many 60 dm³ bags fit in 1 cubic meter, first convert 1 cubic meter to cubic decimeters: 1 cubic meter equals 1,000 dm³. Then, divide 1,000 dm³ by 60 dm³ per bag, which gives you approximately 16.67. Therefore, you can fit 16 full 60 dm³ bags in 1 cubic meter, with some volume remaining.
According to the related link below; the required amount to cover 1 square yard with 4 inches of concrete is 6.6 60 pounds bags.
To determine how many 60-pound bags of sand are needed for 4 yards, first convert yards to pounds. One cubic yard of sand weighs approximately 1,000 to 1,200 pounds, depending on the type of sand. Assuming an average weight of 1,000 pounds per yard, 4 yards would weigh around 4,000 pounds. Dividing 4,000 pounds by 60 pounds per bag gives you about 67 bags of sand needed.
