Official answer
6,514
windows
How to estimate it
Fermi’s official “Napkin math”
Start with how tall it is: 102 floors. How many windows would ring one floor? Maybe 65, once you go all the way around.
- Floors in the building
- 102
- Windows per floor
- ≈ 65
- 102 × 65
- ≈ 6,600
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
