This is a one-dimensional thought experiment. The default 40,000 km is a rounded illustrative target, not a precise equatorial or meridional circumference. A human’s width is an explicit assumption, not a universal biological average. One gap is allocated per repeated unit; closed loops, terrain, physical feasibility and safety are not modeled. Source a scientific or anatomical claim before using it in marketing.
An illustrative 40,000 km target and 0.50 m per repeat unit require 80,000,000 units.
Inspect the assumptions and limits before applying a result.
