There is no such thing as a 3d hexagon.There cannot be a 3d shape with regular identical hexagons. A 3d shape with 6 faces is called a hexahedron, and there are several topologically different variants.
Well if the top it pointed i would call it a pyramid.
Prism
If the base of the pyramid is square, it must have four triangular vertical faces in order to meet at the apex (top). Such a 3D shape is a "square pyramid".
