How does the pressure exerted by the brick on the support change if it is placed on different faces?

Since the pressure of the brick on the support is determined only by gravity, no matter how we place the brick on the support, its mass will remain unchanged, and therefore the magnitude of the pressure on the support as a whole will not change.

When the position of the brick changes, only the value of the specific pressure per unit of support area changes, and the smaller the contact area of the brick surface with the support surface, the higher the value of this specific pressure.
