A ruler would do the trick.

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 would measure it in centimeters.
Depending on the size of it id say either a 15cm ruler or a 30cm ruler.

you measure the length of AA pencil or a pen in cm
If you have to measure the pencil to a couple decimal places i would suggest a micrometer and a dial caliper.
The easy way to find the length of a pencil is to use a ruler to measure it. A "small" ruler might not make it, but a "regular" one foot ruler will do the job nicely.

To measure a pencil case, use a ruler or measuring tape to determine its length, width, and height. Measure the length from one end to the other, the width across the front, and the height from the base to the top. For cylindrical pencil cases, measure the diameter and height instead. Record the measurements in centimeters or inches for accuracy.

grams (for their mass), centimetres (for length), millimetres (for thickness/height), possibly Mohs scale for hardness.
