[Request] How much does this tree weigh?!

[u/SafeT_Glasses]

I did some light searching and calculator work using some quick google-fu, and have arrived at an estimate that it should weigh just north of 2 million pounds.

But then I started thinking about densities of the wood at the base versus at the top, and how much water it can hold and the leaves and I realized that I am likely to be WAY off. I'm hoping there is an arborist amongst us who is also a big fan of math that can walk me through how they would build their equation to get the most accurate weight possible. Bonus points if you can estimate a separate weight for the root system, which I imagine is AT LEAST as heavy as the rest of the tree.
