A three dimensional figure with polygonal faces is called a polyhedron. Specific names draw from the Latin prefixes. For example a four sided figure is a tetrahedron.
A polyhedron (solid shape formed by plane faces) with four faces is called a tetrahedron.
The solid shape that has one square face and four triangular faces is called a pyramid. If you were to have a shape that had four triangular faces and no square face, it would be called a triangular pyramid.
A three dimensional triangular figure with three faces and a base is called a triangular pyramid. It has four vertices, four faces, and six edges.

A square is not a solid figure at all. It's a flat figure, with four congruent faces and four congruent angles.
A three dimensional figure with polygonal faces is called a polyhedron. Specific names draw from the Latin prefixes. For example a four sided figure is a tetrahedron.
A cuboid.
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.
Four triangular faces.
A four-faced solid is called a tetrahedron.
Tetrahedron
The answer is a pyramid.
