A rectangle has only two dimensions, i.e., length and breadth, hence, it is flat. Objects
that have only two dimensions are called 2D or two-dimensional objects.
Now, look at this cuboid and observe the dimensions involved in
its shape. The objects that have three dimensions are called 3D
or three-dimensional objects.
