Can you solve it? Are you smarter than an architect?

Something to stretch the grey cells . It completely flummoxes me.

Uhhhh. I don’t know. Circles don’t have sides, so a slightly smaller triangle? :sweat:

Edit: That’s an equilateral triangle, right? So it wouldn’t fit in the circle because the height would be larger than 1 unit?
2: Never mind, the height would be smaller of course. :disappointed_relieved:
3: Looking at the drawings, I think a slightly different triangle would fit in all and touch all the sides and the circle if you rotated it a little.
4: Never mind, it wouldn’t. I give up. :sob:

the circle messes up all of my guesses… I have no answer… i will guess a cube… i changed my answer… i said diamond at first… but it must be a 3d object… and a cube tilted sideways is a diamond shape…

What about a tetrahedron? :thinking:

i think you figured it out… it looks like you could rotate it to fit any of the shapes…when do we get to know the answer? i retract my answer due to the tree lords great answer…

I’ll be back at 5pm UK time with the solution.

Is what he says.

There’s a correction.

CORRECTION: The image has been updated to specify that the width and the height of the triangle are one unit. In the original image all the sides of the triangle were 1 unit. While I’m here, I will clarify the question, in response to some of the comments below. The object must be made of a solid that is not elastic and does not squash, and it must fit through each of the holes such that when it is going through each hole it is touching every point on the inside of that hole.

Too complex I give up. :fearful::fearful::fearful:

so one section ought to be a circle, another section a square, and another section a triangle…
good luck with that :smile:

I am sure some of our mathematical whiz kids will solve it. I’m like you @anon80629714
,wouldn’t know where to start to work it out.

I found the answer pretty quickly with Google. :smile: I’m not going to spoil it for the rest of you. But you will think “why didn’t I think of that before?”.
PS: No mathematics required. Just simple logic.

but if one section is the exact circle it… the circle side would never pass through the triangle hole… unless when you present the triangle side… the circle side is skewed to fit… never mind sorry lol

Let’s imagine a cone. It has a circular base right? And its projection on a plane perpendicular on its base will be a triangle. I have attached an image for better clarification.
So the problem is 2/3 solved. But that damned square…

Actually I think I have solved the problem in my head :slight_smile: But can’t draw a 3d image of it…

You’re literally one tiny step away from the answer.

It requires some creative thinking .Having seen the solution.

I think logical thinking is enough. You don’t really have to be creative, you just have to understand the requirements for the solution and deduce the answer. But the guy who wrote that article needs to work on how he explains things. I misunderstood him completely. I don’t think I would have reached the answer easily even if he had explained it better, though. I think Andrey is better at this than I am.

No. :neutral_face::rugby_football::rugby_football::rugby_football::neutral_face::neutral_face:

Here’s an attempt to describe my solution, which I can visualise perfectly in my head but have a hard time drawing…
So a 3d object whose sections are: circle (horizontal plane), and square and triangle in the two vertical planes…
Viewed from above or from below it will resemble a circle… viewed from the left it will seem like a triangle… viewed from the right it will look like a square. I can’t describe it any better than this in words… Here’s the photo.
