This is an impossible three-dimensional figure. A pyramid has 5 faces and 8 edges but has 5 corners, not 4. A 4-cornered three-dimensional figure has only one itteration: that of a 4 sided pyramid of 6 edges. Since your shape is 5 sided with 8 edges I would say you have got a number wrong there somewhere.
I AM A SPACE FIGURE WITH 5 FACES, 8 EDGES, AND 4 CORNERS. which SPACE FIGURE AM i?
pyramid
that is a cube
In a polyhedron, there are edges, faces, and corners. The thing that is similar, or common, between the edges, faces, and corners are the vertices.

pyramid
rectangular pyramid
Rectangular prism
that is a cube
In a polyhedron, there are edges, faces, and corners. The thing that is similar, or common, between the edges, faces, and corners are the vertices.
A cube has 6 faces, 12 edges, and 8 vertices (corners.)
A square based pyramid
A pyramid has 5 faces, 5 corners and 8 edges corners and faces are always the same
5 faces 9 edges 6 corners
12 edges 6 faces 8 corners
Zero corners and edges, and a cyllindar has two faces.
