The pencil line is made out of carbon atoms. Assuming that the average diameter of a carbon atom is 3.49x10^-10m, how many atoms thick is the pencil?

ya gotta tell us something about the size of the pencil or its drawn line, or something. A little proofreading can improve your chances of getting meaningful help.

Then there's the composition of the pencil lead. It's not pure carbon. And are yu assuming that the carbon atoms are jammed right next to each other?
