For the great lakes I was off by so many order of magnitudes I'm too embarassed to go count them. Probably about ten.

Me too. 5 out of 10, and the ones I missed were close, except for that one. Couldn't figure out how I was that far wrong. So I took another look at the answers.

23,000 cubic kilometers
6.8 x 10^20 cubic meters

The first seems reasonable. 230km by 100km by 1km deep. The second seems ... wrong and just weird. 2.3 x 10^4 cubic km would be 2.3 x 10^13 cubic meters.
