The 3D shape made up of 4 triangles and 1 square is a square pyramid. It has a square base and four triangular faces that converge at a single point, known as the apex. The triangular faces are the lateral sides of the pyramid, while the square forms the base.
There can be no closed 3D shape with only one square and 3 triangles.
