For the CxxC part,is this for cities that without culture expanded?How exactly is CxxxC?[/quote]
-->CxxC means spacing your cities like this: City-tile-tile-city
-->CxxxC means City-tile-tile-tile-city
I place cities at that range, regardless of whether their culture has expanded. One of the main reasons for that is to avoid unworked tiles.
Cultural expansion and the fat cross are two separate, but related, concepts. In order for a citizen to work a tile, two requirements must be met. First, the tile must be within your cultural borders. This generally means that the tile in question is either immediately adjacent to your city, or your cultural borders have expanded. (I think there are certain situations when planting a city just right will sweep an extra tile under your borders, but I'm not very clear on that, so let's ignore it until someone smarter comes along.) The other requirement is that it be inside the fat cross. The fat cross represents the maximum tiles that your city will ever be able to work, regardless of cultural boundaries. It is 21 tiles large and looks like this:
UxxxU
xxxxx
xxCxx
xxxxx
UxxxU
where:
U = unreachable tile
x = workable tile
C = city tile.
So there's not much range to compute on the fat cross. If you look in the city view, or use Civ Assist II, they'll show you the fat cross.
Does that clarify things or did I totally misunderstand your post?

About the "fat cross"i try to compute the range,but i always end up having one tile unworked which in the angle of the cross.
