Is it possible to determine which side of a GameObject a raycast has just hit?

I wan’t to do this becasue I wan’t you to be able to click a surface in a 3D world, and an object will be placed on that surface whith it’s top facing straight up/away from the clicked surface. (Image below)

The typical solution is to use the RaycastHit.normal. This line of code executed on the object to aligned will align it with the surface:

  transform.rotation = Quaternion.FromToRotation(transform.up, hit.normal) * transform.rotation;
