Usually concrete mix comes in 40, 60 or 80 pound bags.
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.
To calculate the amount of concrete mix needed for an 18x20x4 pad, first determine the volume in cubic feet: 18 ft × 20 ft × 4 ft = 1,440 cubic feet. Since a standard 80 lb bag of concrete mix yields about 0.6 cubic feet, you would need approximately 2,400 bags (1,440 ÷ 0.6 = 2,400). Therefore, you'll need around 2,400 bags of 80 lb concrete mix for the project.

To determine how many 80 lb. bags of concrete mix are needed to fill an oil drum, first calculate the volume of the drum. A standard oil drum has a capacity of about 55 gallons, which is approximately 0.2 cubic meters or 7.4 cubic feet. Since an 80 lb. bag of concrete mix typically covers about 0.6 cubic feet, you would need roughly 12 to 13 bags to fill the drum completely.
Dependant on if you have additives with the concrete and how much water is in the mix. In general concrete will achieve 80 - 90 percent strength within in 24 hours

it takes 45 Bags of 80# mix to make a cubic yard
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.
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.

First, things are not made of cement- they are made of concrete- which consists of cement, sand, gravel and water. Mix them using 1 part cement, 1.5 parts sand, 3 parts gravel. To calculate how much CONCRETE you need, multiply depth X width X length in inches, then divide by 1728. This will tell you the number of cubic FEET of concrete. To get the number of cubic YARDS, divide the cubic feet by 27. If you are using packaged concrete mix (Sakrete is one) then an 80 lb bag makes 0.6 cubic feet of concrete. NOTE: If you are working with concrete for the first time- do not add too much water (weakens the concrete) and do not get wet concrete on bare skin- it will cause a chemical burn. Wash it off promptly if you do.

To prepare an 80% glycerol solution, you would mix 80 parts glycerol with 20 parts water. For example, you could mix 80 mL of glycerol with 20 mL of water to make 100 mL of an 80% glycerol solution. Make sure to thoroughly mix the glycerol and water until the solution is homogenous.
At least in the Albany area it is between $80 to $100 per yard depending on the mix
