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.
Usually concrete mix comes in 40, 60 or 80 pound bags.
This cannot be answered without knowing the width and depth.
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.

One cubic yard of concrete typically weighs about 4,000 pounds. Since each 80-pound bag of concrete contains approximately 0.6 cubic feet, you would need about 45 bags to equal one cubic yard of concrete. Specifically, 1 cubic yard equals 27 cubic feet, so dividing 27 by 0.6 gives you around 45 bags.

Usually concrete mix comes in 40, 60 or 80 pound bags.
This cannot be answered without knowing the width and depth.
Typically, one 50-pound bag of concrete is needed per fence post.
Forty five 80 pound bags of cement are needed to make one cubic yard of concrete.
Depending on the use of the concrete, between 5-6 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.
According to the FAQ on the Sakrete web site, Sixty of their sixty pound bags of High Strength concrete mix will be required to make a cubic yard of concrete.

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.
The number of bags of concrete needed for setting fence posts depends on the size and number of posts. Typically, one 50-pound bag of concrete is enough for one 4x4 fence post. So, if you have 10 fence posts, you would need 10 bags of concrete.
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.
