Sounds like a math problem to me. Don't you have the information you need right here? If you know the size and volume of a grain of sand and the volume of a cup, I think you could figure it out, But then again I'm no math genius.

Using the volume of 1.3 * 10^-9 cubic feet - you would need 7692307.69 grains of sand to fill one cup. (rounded to 2 significant digits)
The range of 1.13 × 10^-13 m3 and 4.85 × 10^-9 m3 is a pretty huge range. The smallest volume would require 2097345132.74 grains, the largest 48865.98 grains.

so between 48,000 and two billion grains?

(After a 10 month delay)... yes.

I am sorry. That range is just unacceptable. I need the answer within a range of one hundred thousand grains, not 1,999,952,000 grains.

Then you need to specify the size of the grain of sand.
But.. using the size given by gomath, the answer is 7,692,308 grains.

let's say the grain of sand is spherical. Would we need to take into account the spacing between each grain. I know it might be insignificant but lets say for example I wanted to know how many Jelly beans are in a cup. Wouldn't that have impact on the accuracy of the true result?
