Mathematically:If the pin has no head:

Measure the length (l), measure the diameter (d) V = pi * R2 * H = 3,14159 * (d/2)2 * l

If there is a head approximate the volume as a sphere or cylinder and add the two together.

Experimentally:
  1. Get two graduated cylinders, ONE and TWO
  2. Count as many pins as you can fit into cylinder ONE (do not go above the top line of the graduation) leave them in that cylinder.
  3. Put water or another suitable liquid into graduated cylinder TWO (make sure you measure the volume of liquid accurately),
  4. Pour the liquid from TWO into cylinder ONE until the pins are all covered and you reach the marking on cylinder ONE that corresponds to the volume of liquid that you started out with in cylinder TWO. Make sure there are no air bubbles trapped between the pins.
  5. Read off the volume remaining in cylinder TWO. That is the volume of all the pins.
  6. Divide the total volume by the number of pins - that is the average volume of one pin
