How many bags of cement does one need . . .

There are all sorts of experimenters speaking with more or less authority on how to calculate how much cement you need for a project. I have tried myself, and it is getting rather confusing, at least for me.
Is there anyone out there who could say "from their experience" approximately how many bags of cement you need for, say, a 20ft or 30 ft dome, or whatever their experience has been?
Perhaps better still, how to do the calculation?
