It could be a rectangle-based pyramid.
A square pyramid
A cuboid.
One - a rectangle is a flat shape - not a three dimensional object !
A rectangle is a two-dimensional shape, so it doesn't have faces in the way that three dimensional shapes have. A rectangle has four edges and four corners.
A rectangle is a two-dimensional shape and does not have vertical faces. Instead, it has four edges and four vertices. If you are referring to a rectangular prism (a three-dimensional shape), it has six faces, with four of those being vertical.
A cube
A pyramid with a square base.
A circle has no faces. In geometric terms, a face refers to a flat surface that forms part of the boundary of a three-dimensional object. Since a circle is a two-dimensional shape, it does not possess any faces.
Because a rectangle is not three-dimensional it does not contain a volume but an area. A geometrical figure that is more efficient than a rectangle for area is a circle.

The shape described is a triangular prism.
A geometric shape with 4 vertices, 4 edges, and 4 faces is a tetrahedron. It is a type of polyhedron that is formed by connecting four triangular faces. Each vertex connects to three edges, and the arrangement of the faces creates a three-dimensional solid. Tetrahedrons are one of the simplest forms of three-dimensional shapes.
