Well, isn't that just delightful! It sounds like A is a special kind of shape called a polyhedron. You see, in a polyhedron, each edge connects two faces together. So if A has twice as many edges as faces, it must be a very harmonious shape with a lovely balance between its edges and faces.

It is not any kind of simply connected solid figure because it does not satisfy the Euler characteristic which requires thatFaces + Vertices = Edges + 2It is not any kind of simply connected solid figure because it does not satisfy the Euler characteristic which requires thatFaces + Vertices = Edges + 2It is not any kind of simply connected solid figure because it does not satisfy the Euler characteristic which requires thatFaces + Vertices = Edges + 2It is not any kind of simply connected solid figure because it does not satisfy the Euler characteristic which requires thatFaces + Vertices = Edges + 2

Bipyramids are a class of polyhedra with more faces than vertices.
A cube.
A pyramid
what kind of pyramid?
An octagon based pyramid.
A platonic solid is a special kind of polyhedron. A polyhedron is a 3-D figure whose faces are polygons.In a platonic solid all faces are identical regular polygons. A polyhedron has faces, edges, and vertices. The numbers of each are related by Euler's formula, V+F=E+2
rectangular pyramid, square-based pyramid, trapezoidal pyramid any pyramid whose base is a shape with only four sides
