Cone
A cone.
There is no shape which has identical parallelogram faces.
A cube
A cube is a 3D shape with a top and bottom.
Well if the top it pointed i would call it a pyramid.
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.
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".
A cube is a 3D shape characterised by six identical square faces and 8 vertices.
If you take a regular four sided pyramid and chop off the top, parallel with the base, the left over piece would be a solid with four identical trapezoidal faces and a square top and bottom. The only name I know is 3-D trapezoid.
The 3D shape with one face and one vertex is a cone. A cone has a circular base that serves as its singular face, while the point at the top where all the lines from the base converge is the vertex. It can also be considered an apex, where the shape tapers to a single point.
