It is sometimes called the base.
Its a pentagonal prism.
A 3-dimensional rhombus is called a rhomboid. It is the crystaline shape of mica.
A cube can be called a cube or a 3 dimensional shape.
It depends on the shape. The top of a pyramid will be a point (the apex). The top (and bottom) of a prism or an antiprism will be congruent polygons.

depends on if it is a 2 dimensional shape or 3 dimensional shape. Please be more specific.
A 3-dimensional rhombus is called a rhomboid. It is the crystaline shape of mica.
A cube can be called a cube or a 3 dimensional shape.
If its 2-dimensional then its an octagon, if it is 3-dimensional then it is called an octahedron.
It depends on the shape. The top of a pyramid will be a point (the apex). The top (and bottom) of a prism or an antiprism will be congruent polygons.
a polyhedron (if the shape is 3 dimensional) a polygon if it is a planar shape.
A shape with 6 sides is called a hexagon. It's a two-dimensional flat shape with straight sides. The word "hexagon" comes from the Greek words "hexa" meaning "six" and "gonia" meaning "corner" or "angle". So, a hexagon has six corners and six angles as well.
