Thanks for bumping this thread! If I remember correctly, my son turned in a number well north of the 1.2 billion I originally discussed. However there turned out to be no right answer as one cannot possibly know the number of trees in the United States to any degree of precision. The teacher was more interested in the methodology that the students used to come up with their best answer.

My son just graduated college this past weekend so I'm thinking this little exercise nearly a decade ago helped to make him smarter.

That is great ... :)

So the teacher didn’t pitch a hissy fit? lol!

In Oregon there is ~ 30 million acres of forest land, each with ~ 100-200 trees, we also have tons of trees in cities and towns and outside designated forest land, so just in Oregon there is many times the total amount of trees you assumed were in the entire US. Nevada has lots of joshua trees and Hawaii has tons of trees too.
