The Back Story:

Why are manhole covers round?  

 Microsoft, the computer software giant, notoriously asked this question in job-interviews. One practical answer being, ”Manhole covers are round because manholes are round.”

In addition to aesthetics and tradition, the round shaped manhole cover cannot fall through its circular opening. A square or rectangular cover may fall-in if inserted diagonally. Circular covers do not need to be rotated to align them properly. A round manhole cover can be rolled and therefore, more easily moved. Also, cylindrical holes are easier to dig, and coincidently, the cross-section of a human beings’ body is roughly circular.
