Any metric unit would do. But it might be easier to pick something smaller than the length of the pencil, like a centimeter, or a millimeter.
Less, the more you use it.
about 25 to 27

Yes you have to use the pythagorean theorm to find the length of a right triangle. But you must subtract A2 from C2 then square root the answer.

For finding accurate volume of a pencil use a vernier calliper, which measures diameter up to two significant figures. For finding volume of a pencil you will need radius (r) and length (L) of the pencil. V = 3.14 r²L
centimeter
A ruler would do the trick.
