How do you get the answer to this problem? The Diameter of a typical pinhead is 1 milimeter. If a common virus measures 250 nanometers in diameter, and the virus fits together so well that there are no gaps or overlaps, how many viruses would fit on the pinhead? Express your answer to the nearest whole number.
