A pyramid has 1 square base.
square base pyramid
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.

The 3D shape with one face and one vertex is a cone. A cone has a circular base that serves as its singular face, while the point at the top where all the lines from the base converge is the vertex. It can also be considered an apex, where the shape tapers to a single point.
A 3D shape with one vertex is called a cone. It has a circular base and a single apex (the vertex) where all the lines from the base converge. The shape tapers smoothly from the base to the vertex, creating a pointed top. Other examples of shapes with one vertex include certain types of pyramids, but cones are the most common reference for this characteristic.

the cone.
Is a PYRAMID NB Do NOT confuse with a TETRAHEDRON, which is three triangles on a triangular base. Thereby making a shape of FOUR sides.

2D is a shape or an object that is flat and u can not pick it up, and it has 2 faces. 3D is a shape or an object that is a shape and you cant pick it up and hold it, and it can have as many faces.
