This is in fact the right one IMO, so I made a mistake. Here we go:
1 cubic acre = square root of 4047 m2 to the power of 3 = 257454 m3
3 cubic acres = 3 times 257454 m3 = 772362 m3
Now, to get the height we'll have to take the cubical root of that value:
ca. 92 meters.

gave us 110 meters, so I guess (by taking the average of in this context
known perversities) that the conclusion of this silly "investigation" is:
The height of Scrooge's money bin is approximately
100 m

give or take a few! How do you like that for an engineer's thumb rule? :-)
