What is dimension mean?

Answer 1

There are two meanings of the word "DIMENSION." The first is the height, width, and length of an object. Say, a box is 5 ft (height) by 6 ft (width) by 9 ft (length). The box's dimensions are 5 ft x 6 ft x 9 ft.

Another meaning of the word "DIMENSION" is a unique place of existence. The higher the dimension, the more variables there are.

For example:

0-D: It is a singularity. It can move in 0 directions.

1-D: It is a straight line. It can move in 2 directions, and has the characteristic of width.

2-D: It is a flat box. It can move in 4 directions, and has the characteristics of height and width.

3-D: It is a cube. It can move in 6 directions, and has the characteristics of height, width, and length.

4-D: We are 4-D. We can move in 6 directions, and have not only height, width, and length, we also have time.
