It is a plane figure. It need no have any specific shape with a name.
A two-dimensional object is an object that can be drawn on a flat sheet of paper. It's called "two-dimensional" because it has 2 dimensions . . . length and width, but no height.
The area of the object.
A two-dimensional shape with six sides is a hexagon. A three-dimensional object with six square faces is a hexahedron.
It is a polyhedron.
Area is a two-dimensional measurement. It tells you how big a two dimensional object is or how large the surface of a three-dimensional object is.Volume is a three dimensional measurement. It tells you how big the inside of a three-dimensional object is or how much a three-dimensional object can hold inside.
Every object is 3 dimensional, no matter how flat they are!
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.

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 area of the object.
The flat plane Postulate, shows another way that one dimensional object relate to the two-dimensional plane.
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.
Two dimensional object is a plane figure where as three dimensional object is solid (space) figure.
A polyhedron.
2d is 2 dimensional, or a flat object.
Assuming that a flat refers to a plane shape, you cannot. A flat is a two-dimensional object whereas a cube is 3-d. The two exist in different mathematical spaces and, according to basic principles of dimensional analysis, direct comparison between the two is not valid.
A planar projection is one wherein the points from a three-dimensional object are mapped on a two dimensional surface. One example is seen when a map of the world is projected on a flat page.
