Every 80lb concrete bag should be mixed with 4 quarts or 3.7 liters of water. This mixture will allow you to place aproximately .60cu/ft of concrete. There are 27 cu/ft in a cu/yd. The number then becomes .0222 yards per 80lb bag. Therefore 45 bags of 80lb (4000 psi) concrete ready mix will be enough for 1 yard of concrete.
The weight of a concrete 80 lb bag is 80 pounds.
This all depends on the mix you want. I assume you mean cement when you mention the 80lb bag of concrete. I have pushed concrete in my day... Bag cement mix is the same as concrete. Don't be funny. How many 80 pound bags will make 1 yard of concrete? I want a definitive answer this time.
300lbs
An 80 lb bag of Sakrete typically requires about 2.5 quarts of water for mixing.
To determine how many bags of 80 lb concrete make a cubic yard, you need to know that one cubic yard is equivalent to 27 cubic feet. An 80 lb bag of concrete typically covers about 0.6 cubic feet. Therefore, to fill one cubic yard, you would need approximately 45 bags of 80 lb concrete (27 cubic feet ÷ 0.6 cubic feet per bag ≈ 45).

P.S.- how did you find this out? Do you weigh 80 lb. bags of cement for fun? rofl ^_^
80 lb bag yields about 0.6 cu ft per Quikrete specs:fNote: the question really refers to concrete not cement.
An 80 lb bag of concrete typically yields about 0.6 cubic feet when mixed. Since there are 27 cubic feet in a cubic yard, half a cubic yard is 13.5 cubic feet. To find how many 80 lb bags are needed, divide 13.5 by 0.6, which equals approximately 22.5 bags. Therefore, you would need about 23 bags of 80 lb concrete to fill half a cubic yard.
To calculate the number of 80 lb bags needed for a 3x4x3 pad, first determine the volume of the pad in cubic feet: 3 ft x 4 ft x 3 ft = 36 cubic feet. An 80 lb bag of concrete typically covers about 0.6 cubic feet. Therefore, you would need approximately 36 / 0.6 = 60 bags of 80 lb concrete to fill the pad.
Typically, a 90 lb bag of concrete mix would require around 1.8 lbs of lime if using a 2:1 ratio of sand to cement. However, it's essential to follow the manufacturer's instructions on the concrete mix bag for the correct proportions for your specific project.
A 5lb bag of anything is 80 ounces.
