a 3D shape has 3 dimensions; length, with and depth
A 3D shape must have length x width x depth.
Adding depth makes a 3D object from a 2D shape.
A cut diamond is a 3D object as it has length, width and depth (even if it is roundish like a pebble)
A sheet of A4 paper could be classed as a plane 2D shape, as it has length x width. A shoebox is an example of a 3D shape, as it has length x width x depth.

2d is a flat shape with only 2 dimentions (width & length) 3d is a shape with 3 dimensions (width, length and depth)

A rhombus is a four sided polygon, a quadrilateral. It is a 2d shape. 2d shapes have 2 dimensions, like length and width. 3d shapes have 3 dimensions, like length, width and depth.
The difference between 2d and 3d shapes is that, a 2d shape is flat, has no volume and depth and cannot be handled while a 3d shape can be held, has depth, volume and can hold things inside it. These are the dimensional shapes which are mostly used in geometry.

3D stands for three dimensional. If a shape has length, width, and depth, then it has three dimensions, thus it is 3D.
It depends on the 3d shape.
It is not a 3D shape.
