a square
There is no solid figure with only four edges. The smallest solid figure is the tetrahedron, made up of four triangular faces, but it has six edges.
I AM A SPACE FIGURE WITH 5 FACES, 8 EDGES, AND 4 CORNERS. which SPACE FIGURE AM i?
There is no such figure.
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.

A triangular pyramid.
A triangular pyramid has 4 faces and has 6 edges
A 3-sided pyramid.
A tetrahedron is a solid figure with 6 edges. There's no such thing as solid edges. A tetrahedron is a triangular pyramid, with 4 vertices, 6 edges and 4 triangular faces. In a regular tetrahedron (the first Platonic solid) all triangles are equilateral.
