It is a frustum of a rectangular pyramid.
If it is a right pyramid then four, otherwise one or none.
Rectangular-based pyramid

A triangular-based pyramid, also known as a tetrahedron, has six lines of symmetry. Each line of symmetry can be drawn from a vertex of the triangular base to the opposite face, as well as along the medians of the triangular base. This symmetry reflects the pyramid's regularity and equal edge lengths in a regular tetrahedron.
a square based pyrmaid has 24 lines of symitry
A triangular based pyramid has no lines of symmetry. However, if each of the non-base triangular sides are equal it will have 3 planes of symmetry. If the base triangle is also equal, it will have 6 planes of symmetry.
It is a frustum of a rectangular pyramid.
I don't really understand your question, but one example of a rectangular based pyramid is the Great Pyramid in Giza.
In trigonometry, we call it a rectangular pyramid.
A rectangle based pyramid!
a rectangular based pyramid
A rectangular prism has 8 vertices whereas rectangular based pyramid has 5 vertices
A rectangular based pyramid has 5 vertices, 8 edges and 5 faces
a rectangular based pyramid has got 6 edges and four faces and four vertices.
The best way to describe it unambiguously is calling it a rectangle based pyramid.
