It cannot be a polyhedron nor any "normal" 3d shape.
A 3D shape that has 4 corners and 4 faces is a tetrahedron. A tetrahedron consists of four triangular faces, with each vertex (corner) where three edges meet. It is one of the simplest three-dimensional shapes and is classified as a type of polyhedron.
There is no 3-d shape with 4 and 1 = 5 triangular faces.
-1
There is no shape with 4 faces and 3 vertices
The geometric shape that has 1 square face and 4 triangular faces is a pyramid. A pyramid also has five vertices and eight edges. The square acts as the base for the shape on which it sits.

None. A shape with four faces is a tetrahedron and that has 4 vertices, not 6.
