There are many different shapes, sizes, and types of pencils. A common shape is round, about 7.5 mm dia., with graphite lead about 2.0 mm dia. Using the ratio of circular areas, we can estimate the wood content in this pencil at 93%. Most wooden pencils also have an eraser, attached with a bit of metal. By volume, then, this will dilute the wood content. In a new pencil 190 mm long, where 9 mm of that length is eraser, about 95% of the length is "wood". Therefore by volume the wood content reduces from 93% to about 88.5%. In terms of actual volume (and ignoring the metal ferrule), this pencil has an entire volume of 8.4 cc, a "wood" (plus lead) volume of 8.0 cc, or a wood only volume of about 7.4 cc. My coffee cup holds about 175 ml (about 6 fluid ounces), or 175 cc. That means my coffee cup could hold the wood from more than 23 pencils! I will not leave it to someone else to answer this question "by weight". Offhand, I think the test density of the medium density woods used in most pencils would be about 400 kg/m3 (specific gravity near 0.4 g/cc).
Based on my research, Cedar seems to be the most popular. However, pencils can be made from other types of wood.

You sharpen the pencil to put a point on it. Before sharpeners and when pencil wood was much thicker, men cut (whittled) the wood with a knife to make the point.
The wood of a pencil is a renewable source.
The main body of the pencil is made from soft wood which is naturally boyant, the pencil 'lead' is not lead at all but a much lighter substance called graphite. Your pencil is just not heavy enough to sink.
A pencil is made out of wood and lead (graphite)
coal+wood=pencil

Pencil Shavings... They are the little curly wood chips you get when you sharpen a pencil.
The mechanical pencil is more earth friendly because to get regular wood pencils,you have to cut down trees. (wood=trees Duhh)
it is made of wood
A pencil's ferrule is the metal part that connects the wood with the eraser.
they are made of wood because that what machines read
