Yes, you're right. I had the densities of balsa and birch mixed up :-(

I'm a bit curious as to how Ryan got 70 metric tons to be 180,000 lbs 
though. As I recall, 1 metric ton is 1000 kg and 1 kg is 2.2 lbs, so the

70-ton Abrams only masses about 155,000 lbs (must be the M1A2 SEP
version 
though - the M1A1 is only 65 tons/145,000 lbs IIRC?).
