​It took a long time but
after a very detailed calculation
 (I was afraid
​ my computer's microprocessor would overheat)​
I have come to the conclusion ​that 10 times 784 is 7,840

​not 78,400​ as I originally said. That means the critical point is 7,840
meters, about 5 miles, and the sea is that deep in places.
