It depends on the thickness of the application.Concrete bags you buy at the home center are generally labeled with the (in this case fraction of a) cubic yard of concrete it makes - it depends on the weight of the bag (60# or 80#) . The bag manufacturers have calculators on their sites to help you figure out how much you need based on area (and thickness) of the job.
How many 8"X8"X16" concrete hollow block from 50 kg cement
An 80lb bag of concrete you can at your local home improvement store covers about 4 square foot at 2" thick. So you would need about 144 bags of 80lb concrete.

.375 cf per bag / 27 cf per cy = 0.13888 cy per bag 1 cy / 0.13888 cy per bag = 72 bags

How deep? Are you talking about dry mix weight or finished weight? Concrete weighs 150 pounds per cubic foot. So if you have a 6" slab, that's 150# for 2 square feet. For a 4" slab, the same amount will cover 3 square feet. For a 3" slab, 4 square feet. Concrete mix is commonly sold in 80 pound bags. The finished weight is the mix plus the water that gets chemically bound to it. There's a guide on the bag telling how many bags you need for a given area and thickness.
It depends on what the bag contains.

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.
