How many dimensions are there?
The number of dimensions:
There are three dimensions that define the length, breadth, and depth of all the objects in the universe (the and coordinates).
Example of one-dimension :
The line is an example of a one-dimensional object because only one coordinate is required to specify a point on a line.
Example of two-dimension :
The surface of a plane, cylinder or sphere is an example of a two-dimensional object. Two coordinates i.e., (coordinate and coordinate) are needed to specify a point on it.
Example of three-dimension :
The third dimension involves depth (coordinate). A perfect example of a three-dimensional object is a cube, which has length, breadth, height, and hence volume.
Beyond these three visible dimensions, it is believed that there are many more. Scientists believe that time is the fourth dimension.
