P.S.- how did you find this out? Do you weigh 80 lb. bags of cement for fun? rofl ^_^
1 CY = 27 CF. One half yard = 13.5 CF. 13.5 CF /.45 CF per 60 Lb. bag = 30 Bags
Imagine a cube 3' x 3' x 3' . that is a cubic yard. I believe a bag is 1/3 of a yard. No It's less than that one 94 lb bag of Portland cement is one cubic foot. And there are 27 cubic feet in a cubic yard ( 3*3*3 = 27) so an 80 lb bag of premix is a little less than 1/27th

80 lb bag yields about 0.6 cu ft per Quikrete specs:fNote: the question really refers to concrete not cement.
70 lb = 31751.465 g or 31.751 Kilo's
No useful answer can be given without the necessary detail.The question needs to describe whether the cement alone will be used (or whether it will be used with sand, or with sand and aggregate, and what mix ratios), and the depth of the application.
A 94 lb bag of cement consists of 94 lbs of cement. I mean, isn't it obvious? The cement is used to make sidewalks, etc. They dry and is some of what we walk on today. :)
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.

There would be 55-60 cups of uncooked rice in a 25 lb bag, depending on the type of grain of rice.
The amount of cement needed to set a fence post depends on the size and depth of the hole, but typically a 50 lb bag of cement is enough for one post.
Figure about 1/2 cubic foot per 60 lb bag. The basic formula is to use equal amounts of cement, sand, and gravel. There are 27 cubic yards per cubic foot. It depends upon how thick you are planning to pour the concrete. For one foot thick, you would need 9 cubic feet of concrete. For 6" thick, you would need 4 1/2 cubic feet. I'll give you the answers for 1 ft thick and for 6" thick. For 1 foot thick, you need 9 cubic feet at 1/2 cubic foot per 60 lb bag equals 18-60 lb bags. That's six 60 lb bags of concrete, plus six 60 lb bags of sand, plus 360 lbs of gravel. For 6 inches thick, divide each of these by 2 to give 3-60 lb bags of concrete, 3-60 lb bags of sand, plus 180 lbs of gravel.
The answer will depend on how deep a layer of sand.
A good estimate is somewhere between 4 1/2 and 5 gallons in 60 lb of dry sand, depending on how tightly it is packed and how fine the grains are. .
The 30 x0 20 x 4" answer should be for a 50kg bag. A 25kg bag of cement is 43 x 22 x 14 cm according to Blue Circle on Amazon, that is 17" x 8.6" x 5.5" in old money.
