Can't you just see Tim Cook breaststroking through cashmoney? I can.
If you're curious about the calculation, it's actually pretty simple. A dollar bill (according to Wolfram Alpha) has a volume of 0.06943 cubic inches. An Olympic-sized swimming pool has a volume of 152,064,000 cubic inches. Divide the pool by the money and you come up with 2,190,177,157 bills needed to fill a swimming pool. Take Apple's cash position -- roughly $110 billion -- and divide by that number of bills and voila, you get 50.22 pools.
