0.6 cu yds
0.6 yards is incorrect. According to quikrete's website it would require 46 80# bags of concrete to cover 81 square feet at 4" thick, which is one cubic yard. Dividing 46 by 1 yard gives us approximately 0.022 yards per bag.
An 80-pound bag of premixed cement = .667 cubic feet, or 2/3 of a cubic foot, of concrete. A 60-pound bag of premixed cement = .5 cubic feet, or 1/2 of a cubic foot, of concrete.
Usually concrete mix comes in 40, 60 or 80 pound bags.
1.8 Cubic yards of concrete is 48.6 cubic feet. Each 80lb bag of concrete is .6 cubic feet. Therefore, you would need 81 bags. Hope that helps. GEO
I assumed here that you wanted a wall six inches thick...the answer is "more bags than you want to deal with." Specifically, at least 125 80-pound bags. The formula is: first, determine the volume of the item by multiplying the height (3 feet) by the length (50 feet) by the thickness (0.5 feet). This gives you 75 cubic feet. If the wall's thinner or thicker, of course this is going to change. Next, divide this by the number of cubic feet in a bag-- 0.30 cf per 40 pound bag 0.45 cf per 60 pound bag 0.60 cf per 80 pound bag This gives us our total bags...125 80-pound, 167 60-pound or 250 40-pound. Then add 10 percent more, just in case. This is the time I'd start thinking of other things to make from concrete, so I could order five yards of it. Five yards of premixed concrete will be cheaper than the three yards of bagged concrete you'll need, and you can't mix concrete fast enough to pour something this big.
0.6 cubic feet in one 80 lb bag. with there being 27 cubic feet in one cubic yard: 0.02 cubic yards per bag, in other words, it would take 45 - 80lb bags to yeild 1 cubic yard of concrete
it takes 45 Bags of 80# mix to make a cubic yard
80 lb bag yields about 0.6 cu ft per Quikrete specs:fNote: the question really refers to concrete not cement.
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.

60 pound of concrete bag makes 1/2 cubic foot of concrete
cubic yards is a volume while a pound is a weight, the question is nonsensical An 80 bag of Quikrete is 0.6 cubic yards, so dividing 0.6 by 80 means that one pound of Quikrete will make 0.0075 cubic yards of concrete.
0.6 cubic feet in one 80 lb bag. with there being 27 cubic feet in one cubic yard: 0.02 cubic yards per bag, in other words, it would take 45 - 80lb bags to yeild 1 cubic yard of concrete
i would take about 54 40 pound bags to make a cubic yard each 40 pound bag is about 1/2 a cubic foot and there are 27 cubic feet per cubic yard.
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.
