10 bags will give you 6'2/3", seven bags will give you 11 bags will give you 7'1/3". Each bag is 2/3 cu feet.
To calculate the number of 80-pound bags of concrete needed for a 2x2 slab that is 6 inches thick, first determine the volume of the slab. The volume is 2 feet x 2 feet x 0.5 feet (6 inches) = 2 cubic feet. An 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, you would need approximately 4 bags (2 cubic feet ÷ 0.6 cubic feet per bag = about 3.33 bags, rounded up to 4).
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 calculate the number of 80-pound bags of concrete needed for a 10 x 10 x 4-foot slab, first determine the volume in cubic feet: 10 x 10 x 4 = 400 cubic feet. Since a standard 80-pound bag of concrete yields about 0.6 cubic feet, divide the total volume by the yield per bag: 400 ÷ 0.6 ≈ 667 bags. Therefore, you would need approximately 667 bags of 80-pound concrete to complete the slab.
To calculate the number of 80-pound bags of Quikrete needed, first determine the volume of the slab in cubic feet. The volume of a slab that is 4 inches deep, 4 feet wide, and 7 feet long is 4/12 (0.33 feet) x 4 feet x 7 feet = approximately 9.33 cubic feet. Quikrete typically covers about 0.6 cubic feet per 80-pound bag, so you would need about 16 bags (9.33 cubic feet ÷ 0.6 cubic feet per bag = 15.55 bags, rounded up to 16).
Depending on the size, bags of ice can be from $1.00 up.
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).
Quikrete is sold in 60 pound bags, therefore we will need 1.5 bags. Each 60 pound bag produces 0.45 cubic feet, so times 1.5; 90# bag will yield 0.675 cubic feet .
That would depend on the density of the bags of topsoil.

To make one cubic yard of concrete using Quikrete, you would need approximately 54 bags of 50-pound Quikrete. This is based on the fact that one cubic yard is equivalent to 27 cubic feet, and a 50-pound bag yields about 0.375 cubic feet of concrete. Therefore, dividing 27 cubic feet by 0.5 cubic feet per bag gives you about 54 bags.
