So, based on your title of this thread, do you mean that this is the amount of square footage of surface area for ALL the 3000 bioballs or is this per cubic foot?
If I'm not mistaken, this should be 286 square feet per cubic foot of media and the 3000 bioballs would be equal to roughly 3 cubic feet. Therefore you would have about 858 square feet of surface area for these bioballs. I don't know the specifics about how they arrive at the numbers they come up with but it has to do with the TOTAL surface area of each bioball. They then measure how many it takes to fill a one cubic foot container and measure out by math for the rest of the calculations.
So, basically, you back into the the amount of media needed by starting with your fish load as Mike's (MCA) chart shows. 100 lbs of fish load requires approx 1500 sq ft of media. If one cubic foot of media equals 286 sq ft then take 1500 divided by 286=5.25 cubic ft. So, if you order 6000 bioballs, you're looking good for 100 lbs of fish load and a pinch to grow on!LOL
