Re: Small Ball Pickup Poll
Well, the balls' Diameter is 13", the vaolume of the sphere is ~1150.3465 cube" (4/3*pi*r^3), the cube containing the ball (length=13") has a volume of 2197 cube". You find the volume of you container and divide by either number. The first will be high, the second will be low.

Re: Small Ball Pickup Poll
