Curious of what an MBB level breakdown would be for this, having difficulty creating answers without over assuming.

Hi!
Please keep it simple! So you could just:
- Estimate (or ask for) the size of area covered by Central Park (let's say 3 square kilometers)
- Make an assumption on the share of the space covered by trees (let's say 50%, the rest is water, grass, walking spaces, etc.)
- Estimate the density of trees (let's say on average one tree needs 10x10m space, so 100 square meters)
- Divide the relevant tree-covered space by the required space per tree --> 1.5 square kilometers = 1.5 million square meters --> 1.5 million / 100 = 15k trees
Please note: this result is equally sensitive to all assumptions (since all elements are connected via multiplications or divisions). Hence, changing an assumption by a certain percentage will directly translate into a corresponding percentage-change in the result (e.g., if the density of trees is halved (--> doubling the the average square meters per tree), the final number of trees will also be halved).
Hope this is helpful!
Cheers, Sidi
Hello!
It´s a simple one, and you can extrapolate it to others such as:
- How many heirs do you have in your head?
- etc.
You need to calculate the area (or stimate) and then stimate a density of trees per unit of area.
In this case, I would stimate per every 10m2, that is something you can "size" in your head.
Hope it helps!
Cheers,
Clara
