3.5 cubic feet, 3 to 1 mix with sand
Twenty-one .75 cubic foot bags equal 16 cubic feet.
1 cubic yard = 27 cubic feet = 54 half-cubic-foot bags
The number of bags of rocks in 12.25 cubic feet will depend on the size and weight of the bags. To determine the number of bags, divide the total volume of rocks (12.25 cubic feet) by the volume of each bag.
To convert cubic feet to cubic yards, divide by 27. If each bag is 2 cubic feet, then 1 cubic yard is equivalent to 13.5 bags of mulch (27 cubic feet ÷ 2 cubic feet per bag). Therefore, 6 cubic yards are equivalent to 81 bags of mulch (6 cubic yards * 13.5 bags per cubic yard).
Nine 3 cubic feet bags equals one cubic yard. There are 27 cubic feet in one cubic yard. 27/3=9
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 .
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.
There are approximately 27 cubic feet in a cubic yard, and an 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, to fill one cubic yard, you would need about 45 bags of 80-pound concrete.
There are 27 cubic feet in a cubic yard, and a 60-pound bag of cement typically yields about 0.45 cubic feet when mixed. To fill one cubic yard, you would need approximately 60 bags of 60-pound cement.
That would depend on the density of the bags of topsoil.
A typical 80-pound bag of concrete mix yields about 0.6 cubic feet of concrete. A 3-yard mixer has a capacity of 81 cubic feet (3 cubic yards). To fill the mixer, you would need approximately 135 bags of 80-pound concrete mix, since 81 cubic feet divided by 0.6 cubic feet per bag equals about 135 bags.
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 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).

10 bags. Each 80 lb bag is 0.6 cubic feet, and your hole is 6 cubic feet.
To determine how many 80-pound bags of concrete are needed to fill a 55-gallon drum, first calculate the volume of the drum. A 55-gallon drum holds about 7.4 cubic feet (since 1 gallon is approximately 0.133 cubic feet). An 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, you would need approximately 12 to 13 bags of concrete to fill the drum.
