Centimetre
Metric ruler
A ruler or tape measure.
To find the volume of a pencil, you can approximate it as a cylinder. Measure the diameter of the pencil to find the radius, and then measure its length. Use the formula for the volume of a cylinder, ( V = \pi r^2 h ), where ( r ) is the radius and ( h ) is the height (length of the pencil). Calculate the volume using these measurements.
You can use millimeters.
Centimetre
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.
