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.
An 80 pound (36.3 kg) bag of premixed concrete mix (concrete and sand) provides about 0.6 cubic feet of concrete when mixed with the recommended amount of water.
If you use Sakrete, there are typically (42) 80lb bags on one palette.

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.

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.
A 5lb bag of anything is 80 ounces.
10 bags. Each 80 lb bag is 0.6 cubic feet, and your hole is 6 cubic feet.
80 meatballs
There is 0.45 cubic feet in a 60-lb bag, so you need 60 bags. If you go to 80-lb bags, there's 0.60 cubic feet and you need 45 bags.
The answer will depend on how wide and deep the grout is applied!
10 80# bags will fill about 6 cubic feet, so 375 bags should fill 225 cubic feet (30 x 30 x 0.25).ANS 2 -At least in my area, it would be much cheaper ordering this to be delivered by a concrete truck.An 80 lb. bag of concrete is 2/3 of a cubic ft. of concrete. 3 bags is 2 cu. ft. So for 225 cu.ft. youll need 338 bags of concrete.
I think one 80 lb. bag will cover about 4 square feet 1 inch thick
