How to estimate it

Fermi’s official “Napkin math”

Start with one play. How long does it run on stage? Call it two and a half hours, with actors talking at maybe 150 words a minute. Times 38 plays, and the poems are a small extra.

Stage time per play
~150 min
Words a minute
× 150
Words per play
≈ 22,500
22,500 × 38 plays
≈ 855,000

Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
