Four, 3 sides and a base.* * * * *A pyramid, in mathematical terms is a 3D shape with a polygonal base (with n sides) and n triangles that meet at an apex. This gives n+1 surfaces in all. n can be 3 or more.5 flat surfaces
A cylinder has 2 flat surfaces and 1 curved surface.In differential geometry, a cylinder is defined more broadly as any ruled surface spanned by a one-parameter family of parallel lines. As such it can have any number of flat surfaces but need not have any at all. A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinderrespectively; these have no flat surfaces.
square
Parrallelogram
All faces on a cube are equal to each other the shape is of the face on a cube is a square
A tetrahedron is a solid figure with four flat surfaces that are triangles. Each face of a tetrahedron is a triangle, making a total of four triangular faces in the shape.
Only one. All squares are figures drawn entirely on a flat surface.
A cylinder
A cube.
A cube has 6 flat surfaces. Most boxes of all shapes also have six flat surfaces
A square based pyramid
A "rectangular" is an adjective, not a noun and so there is no way of knowing what the shape is. It could be a rectangular 2-d shape, a rectangular pyramid, a rectangular prism and they would all have different answers.
No, the top and bottom would be flat however the center is rounded.

The flat surfaces of all polyhedra are called faces and a rectangular prism is simply one kind of polyhedron.
Polygon
Yes and its flat surface faces are in regular shapes.
