A rectangular pyramid is a solid (3-dimensional) figure that comes to a point opposite the base (like the Pyramids of Egypt.) Its base is a four-sided plane figure with right angles and opposite sides equal (a rectangle--or square for that matter).

In the context of geometry, the base of a solid figure refers to a flat surface on which the figure stands, often used to calculate its volume. For three-dimensional shapes like prisms and cylinders, the base is typically a two-dimensional shape (like a rectangle or circle) whose area is multiplied by the height of the figure to determine the volume. In formulas, volume is often expressed as ( V = \text{Base Area} \times \text{Height} ). Thus, the base plays a crucial role in volume calculations.

a square pyramid, perhaps a rectangural prism with a square pyramid on top
No. A flat, 2-dimensional figure can be a quarilateral - a square for instance. A 3-dimensional figure like a sugar cube, which is a solid and has thickness, cannot. For solid shapes, names like 'Parallelepiped and rhombohedron' are used.

A polygon is a many sided 2-dimensional figure, and thus could never be "solid" Alternatively, it could be "one face that is a polygon". In that case the solid could be like a pyramid that morphs into a cone or a part-sphere. The base would be the one polygon, the other face would not.
A three dimensional solid figure looks like a cube or a prism. Pyramids are three dimensional solid figures as well.
