I How do I calculate density given height and volume?

[Godzilla-3301]

I’m trying to calculate how many Joules are stored in the Hyperion tree, the worlds tallest (115.84 m). However, I cannot find the mass of said tree, and am trying to find it by multiplying density by the volume (530 m^3) because if p=m/V then p•V=m, but I cannot find the density of the tree, so how can I find density given height and volume, if it’s possible?

Height and volume are not enough to figure out anything about mass.

That said, you can probably just look up the density of a generic tree and get something close enough.

Alternatively just Google a little harder

an estimated aboveground dry mass of 209 metric tonnes (230 US tons),

One could also find whether it’s a hardwood or softwood and further estimate the density.

Lastly, if there’s any lumber store featuring this wood, you might find the weight of a given plank and compute the density from it.

I found the tree is a redwood and I found this density table

going with American Redwood it’s $28 lbs/ ft^3$

My favorite thing about Google is how it will just do this for you, so you don't even have to worry about the conversion.

The volume estimate in the op + weight estimate in my post give 25 lbs/ cubic foot. Not far off from your number.

I found the tree is a redwood

But what kind of redwood? The three species I know of are Sequoia sempervirens (Coast redwood), Sequoiadendron giganteum (Giant redwood), and Metasequoia glyptostroboides (Dawn redwood).

The Hyperion tree of this thread is almost certainly a Giant Redwood, a type of redwood found in the Sierra Nevada Range of California, especially in Sequoia National Park. The Coast Redwood is found mostly along the coast of Northern California. The Dawn Redwood, which was a new one to me, is found in China.

As a sidenote, I found it interesting that the "sequoia" part of their names is in honor of Sequoyah, a Cherokee who was responsible for the syllabary of that language.
