From the largest manufacturer of backaged Portland Cement, bags come in 92.5 lb bags. To be clear, cement is mixed with sand and often aggregate (pea-gravel up to much larger rocks or other things such as broken out concrete chunks) to make concrete. Portland Cement by itself has no structural integrity when mixed with water. It must be mixed with sand at a minimum to make a hard, useful product (concrete). Concrete comes in bags weighing 50, 60, and 80 pounds here in the US.From the largest manufacturer of backaged Portland Cement, bags come in 92.5 lb bags.

How much does a bag of cement weight? Know that and you have a very simple formula: y = 4000/x where x is how much a bag weights and y is your answer.
8 bags
it depends on the type of mix and water cement ratio.
6 bags.... depending on the mix ratio

according to my books you will need at least 50 bags of 60lbs of cement maybe more but less than 80 bags
4 bags of 50 kg each= 200 kg of cement.
@ 1:5 mix, 15 cement and 71 25kg bags of sand (1,175kgs)
one cubic meter of concrete equals 30 bags(approximately) The exact answer is 28.8 bags of 50kg cement bags. Typical Portland Cement has a density of 94 lbs/cubic foot, which translates to 1505 kg / cubic meter. So, divide 1505 kg by the weight of a "bag" of cement in kg. --------------------------------------------------------------------------------------------- Seems to be perhaps a little confusion here between concrete and cement. Cement is the powder we mix with aggregate to make concrete. Cement varies in density as much as 100%, i.e. it can double in density. From the above URL one 94lb bag is taken to be 1 cu ft for building purposes. 1 cu metre = 35.3146667 cu ft and therefore 1 cu meter of CEMENT is that many 94lb (42kg) bags. Hence the answer for how many Cement bags in 1 cu m = 35.3 94lb bags. It would make more sense if the query was directed towards finding how many bags of cement are required for 1 cu meter of CONCRETE. This depends, of course, on the chosen concrete mix. They vary widely. A most common mix is 1:2:3 - 1 part cement, 2 parts sand, three parts aggregate all by volume. In concrete making the dry ingredients shrink during the process as they compact together. It is found necessary to commence with 1.6 cu m of dry material to finish with 1 cu meter of concrete. 1.6 cu m = 56.5034 cu ft of which the cement portion should be 1/6 for a 1:2:3 mix. 56.5034/6 = 9.4172 cu ft and therefore 9.4172 1 cu ft, 94lb or 42kg bags are required or round about 20 of the usual household DIY worker's 20kg bags here in Australia. Hence the answer for how many bags of cement to make 1 cu m of (1:2:3) concrete is 20 20kg bags. These answers are not precise because of the nature of cement. Refer again to the Portland Cement Association website and their remarks on density.

Production of portland and masonry cement in the United States, excluding Puerto Rico, increased by 2% to 86.4 million metric tons in 2017.
