How to track the side of pressing an object?

Question

Unity

How to track the side of pressing the cube, for example? Like in Minecraft. It is to track that it is not just a click, but on which side of the cube it is.

Answer 1

On stupid - put on a collider on each side of the cube.
According to smart - geometrically - there is a point where the "pressing" comes from - the player\hand. There is a center of the cube. Find the intersection point of this line with the face of the cube.
