 P: 31 If I had a sphere with a radius of 100 meters, a diameter of 200 meters, a volume of 4,188,790.20 square meters, and I wanted to place within this sphere a single dot (one dimensional so it doesn't take up any extra space and there is no displacement --if you're thinking in terms of water--), and I need to have one dot every 50 meters, what is the formula I would use to determine that? I thought it was just divide the volume by the number 50, but that comes out with a large number like 83,775.80, which seems insanely huge for something with just a diameter of 100 meters. What am I doing wrong here? This isn't a homework question, just something I'm trying to throw together for an experiment I'm doing in my personal time.
 Sci Advisor P: 5,942 I presume you are trying to fill the volume of the sphere. You need to divide by 125000 (503) not 50. I got 33. Note volume is cubic meters, not square meters.
 P: 31 Ah ok....that makes SO much more sense! lol
