a square, or oval manhole cover could and obviously eventually would
An even triangle could work fine, but more manufacturing cost + more hassle since it needs aligning to manhole.. a round manhole cover is always aligned with the round manhole...

Don't forget a circle has the minimal area (material) to cover a similar space, so material savings.

I'm guessing you mean 8 + -4?

The problem is, if they were like me I would have to catch the good ones as they tried to walk out.

NFW. I've never been asked. I read about that sort of thing being asked, but there's no way in hell that anyone would be getting my social media pw, and I don't have anything to hide.

A ball of yarn? Or the lower corner of a square sail?
