I wish you were my math teacher, or just my teacher overall.

@tolli111 Yeah, there pretty massive! I live in the Pacific Northwest, so the tallest trees are mostly the douglas fir and the white fir. The white fir is the tallest, as I said about 120-160 feet, but the douglas fir is much thicker in diameter. As said, I have to measure it, but I've compared a length of ground that I know to be 100 feet exactly and compared that to the trees, and there obviously about 1.5 times higher. The highest ones are still only about 4 feet in diameter though.

Thanks so much! I've always wondered exactly how tall the trees in my yard are, as they're very tall, (Until I do what you did it this video, I'm guessing about 150 feet) it'd be very cool to know!

@pagani8 damn! I saw some sequoia's in Yosemite when I went there on vacation...huuuuuge, love nature!

@pagani8 you have trees of 50 meters????

I love your Videos they are so well explained not to mention that English is not my native language
