If you solve this puzzle, you are even better than an architect

The imaginative puzzles of space geometry do not seem to be strong for many people, including architects.

Can you solve this problem?

"Draw a 3D image of an object that can pass through all three holes above, but at the same time also have to contact all the edges of the hole".

Is there anything that looks like that? The answer is yes . The shape is the answer to the above puzzle, depending on the angle of view, it can be a circle, a square, and a triangle.

If you are unfamiliar with imagining 3D cubes, you should start by imagining a cylinder with a bottom diameter of 1 unit of length. This shape will "fit through" the round shape. After that, we will trim this cylindrical block until they finish the other two conditions.

So, our next job is to cut the cylinder block so that the height of the cube is exactly 1 unit of length. This will cause our cube to meet the next condition: "fit" with the square hole, because the cross-section of the main block is a square with sides equal to 1 unit of length.

The last condition, which is also the most difficult condition, is how to cut the block so that it fits well with the triangular hole, while still not affecting the two conditions that we have achieved. original At this step, all we really need to do is to peel the sides of the cube according to the following figure:

How to solve the problem.

Below is another picture of the answer, cut from a banana:

The block is cut from a banana.

If you still can't figure out what the answer looks like, then this is another clip of the answer to the riddle of the beginning:

A block fits in three different types of holes.

At this point, you will probably feel that the puzzle is not as difficult as we originally thought, right?
