Two. Considering this is a two-dimensional object, cut out of a piece of paper it would have two flat surfaces, the front and the back. If your talking a about a sphere, the three-dimensional object of a circle, it has no flat surfaces considering it is round.
The flat surface of any three dimensional object is called a face; a prism is a three dimensional object.A tetrahedron has 4 faces, a cube has 6 faces, an octahedron has 8 faces, etc.
No
One - a rectangle is a flat shape - not a three dimensional object !
Objects that are not flat are any 3-Dimensional objects. A 3-Dimensional object has volume, where as a 2-Dimensional object does not. Examples of 3-Dimensional objects are sphere, cube, and cylinder.
A polyhedron.
In geometry, a circle is a two-dimensional object, so it does not have a surface. Only three-dimensional objects have surfaces. A disc is a flat, circular three-dimensional object.

Polyhedron (plural polyhedra)
No
No, a triangle does not have three faces; it is a two-dimensional shape with three sides and three angles. In three-dimensional geometry, the term "face" refers to the flat surfaces of a solid object, such as a tetrahedron, which has four triangular faces. A triangle itself exists only in a plane and does not have any volume or faces like a three-dimensional shape.
No, a cube is not a flat surface; it is a three-dimensional solid object with six square faces, twelve edges, and eight vertices. Each face of the cube is flat, but the cube itself occupies space in three dimensions. Thus, while it has flat surfaces, it is not considered flat as a whole.
One - a rectangle is a flat shape - not a three dimensional object !
The difference between a "face" and a "flat surface" is found in what is being described by each term. A "face" refers either to the direction of a surface or to the simple fact of a surface as a surface. By contrast, a "flat surface" refers to the quality of the surface in question. Thus, one "face" of a building may be flat, smooth, curved, etc., while another may be similar or different.
