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.

A face is a specific side of a three-dimensional object, while a flat surface refers to a surface that has no curves or bumps. All faces are flat surfaces, but not all flat surfaces are faces on a three-dimensional object.
A face of a polyhedron is one of the flat surfaces. These are two dimensional objects. Two faces meet at an edge, which is a line - a one dimensional object. Three or more edges meet at a vertex which is a point. A point has no dimensions.
The technique or art of depicting a three dimensional (3-D) object on a flat surface.
