Whilst defining an object, length,
width and height parameters are used.
While creating these parameters, its place
in the outer space is also paid attention to.
These processes in mathematics are
executed with the coordinate system. The
place of the object is expressed with the x,
y, z parameters that show the coordinates.
Also in defining an object in plane, on a
map or a photo; and in defining an image
on a machine project, only the width and
length parameters with its most common
form are given. The object and the image
we define in this circumstance are named
as 2B.
