It is a polygonal pyramid.
A polygonal pyramid.
A polyhedron of which one face is a polygon of any number of sides, and the other faces are triangles with a common vertex.
A cube is a solid figure called a polyhedron. A polyhedron is a solid figure with all flat faces. So a cone would be a solid figure but not a polyhedron becasue it has a curve and does not have all flat faces.
A pyramid has a polygonal base with all other sides being triangles. As the Egyptians famously demonstrated, a common pyramid has a square base with four triangles meeting at a vertex, but any polygon - regular or irregular - can be used as the base of such a polyhedron.
Three or more, as many as the number of sides of the base. Pyramids can have base that are triangles, squares rectangles, or any planar polygon.
