@Zest well how would you define a hole? just as an opening?

@Warlock did you read the answer above?

@Zest answer here (hint you are wrong but close)

@b6hydra fair point. You can make the assumption there are no tricks here and both holes are through holes and there are no hidden holes.

@rchrd

That is of course a valid criticism. You would have to make an assumption there of course.

@cee @naccy @Warlock

@rchrd See my answer and explanation here if you'd like.

@apropos

You must be a riot at parties.

@PonyPanda

@xarvos Correct, the answer is white. Reason being black radiates more heat while white radiates less. White behaves like an insulator while black acts a bit like a heat sink for IR.

@PonyPanda It was mostly intended as a joke where I equate children with an STD.

The answer is 7.

In math we count holes by using whats called Geometric Topology, which is really just a fancy way of describing an every day hole in a formal way.

The simplest way I can describe it without getting technical is if you take the shirt and stretch it and flatten it into a disc. That is, take the large opening at the bottom around your waist and stretch it out on a flat surface until it creates a flat dist where the opening around the waist is the outer perimeter of the disc.

At this point count the holes in the disc, you will count 7.

@Warlock

@cee hahah as you wish :) ::pats your head again::

@Warlock

I suspect unless someone has a background in math, or is good at thinking about this in a more generalized way almost no one is going to get the correct answer.

There is a very formal definition for a hole, and as such a formal/technically correct answer. That said its something someone who doesnt know math could probably reason about if they are particularly good at spatial reasoning.

I am happy to give the answer in DM to anyone who asks.

@naccy

@cee hahaha ::pats you on the head:: Do you just want the answer then?

@cee depends on what you call a gotcha. Like i said there is a formal/technical definition of a hole. This question is largely about understanding what that definition is then applying it.

I am happy to walk you through the logic if you want (thus why ia sked you about a cup)

@schnappi You are correct, this question is homosexual. It only has sex with questions of the same gender.

@cee how many holes does a cup (no handle) have?

@cee

its not rigged.. its just 1) there is a detail in the picture people might miss 2) most people dont know what a hole is defined as technically

The answer isnt 6 either.

I kinda expect no one to get this right unless they know math, which is the only formal definition of a hole. But if you think about my hint you can maybe get it without math.

@schnappi Nope, but most people would get this wrong from a technical perspective.

@cee nope
