1) manholes are round
2) simplicity of manufacturing
3) won't fall in
4) no alignment needed to place
5) you can ROLL the lid to where you need it. Those things are HEAVY!!!

So it has nothing to do with the shape and contour of our bowel movements?

[Sri Anand]: Would this answer help?

That wasn't part of what I'd actually say.

I disagree - I think an equilateral triangle could fit through a slightly-smaller equilateral triangular hole fairly easily.



I looked it up, and I stand corrected. A cover shaped as an equilateral triangle could indeed fall through. Still, the round cover is not the only shape to prevent it from falling through. Any Reuleaux polygon would do the job.

Right. And this is true for almost all shapes; the circle is the simplest curve for which the minimum and maximum diameters are equal, but there are others.

But why knowing this should be a useful thing for somebody who is going to be writing applications to keep track of inventories of plumbing fixtures, I don't really know. Perhaps that's another question the HR people could ask. Or the interviewee.

I'm glad you asked me that, because I was a keynote speaker at the 2008 Midwestern Sewage Convention, and the delineation of manhole covers was central to my thesis. You probably saw me on the cover of Time. Although I don't have my PowerPoint presentation with me today, I did happen to bring a manhole cover to use as a visual aid for an unrelated topic. Now, of course, the first manhole covers were observed on the lunar surface via telescope by Irving Berlin, and his crude sketches formed the basis for those preceding his discovery. Uninspired by this, Maurice Ravel "became" a manhole cover for 18 months as a widely misunderstood performance art installation. Are there any questions so far? Good...

I'm glad you asked that question. Yes, there are. For example, some manhole covers in my city have got Northwest Coast native motifs like salmon painted on them. Isn't that cultural appropriation or something?

and wikipedia says

The rotor of the Wankel engine is similar to a Reuleaux triangle.



However, they are hard to machine, so it essentially goes back to "round is the one easy to make shape that will not fall in"

So the correct answer is "not fall in" and you get extra points for Reuleaux polygon, altho you may lose extra points for being a smart ass.

Myriad theories abound (generally in the form of haiku), but the obvious explanation remains the most plausible: Rogue factions of molecular biologists have electro-coated select manhole covers with a thin motif of salmon (or other fish proteins) in an effort to lure rare enzymes into the sewers. Once the enzymes are below ground, the biologists entice them into a game of Monopoly. Some consider this a form of "cultural appropriation."

Ans: Same number of flower shops when I came in this morning.

Kinda old, but kinda relevant..

or may be the answer should be this

Ans: X. where X is an int and X>=0.

or may be the answer can be this:
5 (or some realistic number). I doubt if the interviewer knows exactly. pointless answer to a pointless question.

well, then the interviewer might ask "how come you know there are exactly 5" then may be you can answer: " i just happened to know!" or better yet you can say " i read yellow pages for fun ".

This whole interview 2.0 thing gets me..

-Reuel.
