If the plate is lowered with its edge into the water, then it will sink, if you lower it with the bottom

If the plate is lowered with its edge into the water, then it will sink, if you lower it with the bottom, then it will float on the surface of the water. Why?

A buoyant force acts on any body placed in water. According to Archimedes’ law, this force depends on the volume of a body placed in water, and, in turn, the volume of a body depends on the surface area of this body in contact with water. This means that if we lower the plate with a face, then the area of the plate surface in contact with water is small and the plate sinks. If we lower the plate upside down, then the area of the contacting surface of the plate will be large and the buoyancy force of Archimedes will not allow it to drown.
