Question

What is Dimensions and how to define it

Answer 1

Explanation:

In physics and mathematics, the dimension of a mathematical space is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one because only one coordinate is needed to specify a point on it – for example, the point at 5 on a number line.

Answer 2

Question

What is Dimensions and how to define it ?

Answer:

Dimensions in mathematics are the measure of the size or distance of an object or region or space in one direction. In simpler terms, it is the measurement of the length, width, and height of anything.

There are three dimensions . They are

• One-dimensional (or 1D)  
• Two-dimensional ( or 2D)
• Three-dimensional (or 3D)

Explanation:

Zero Dimensional

A point is a zero-dimensional object as it has no length, width or height.  It has no size. It tells about the location only.

One Dimensional

A line segment drawn on a surface is a one-dimensional object, as it has only length and no width.  

Two Dimensional  

The 2-dimensional shapes or objects in geometry are flat plane figures that have two dimensions – length and width.  Two-dimensional or 2-D shapes do not have any thickness and can be measured in only two faces.  

A square, circle, rectangle, and triangle are examples of two-dimensional objects.  We can classify figures on the basis of the dimensions they have.

Three dimensional

In geometry, three-dimensional shapes are solid figures or objects or shapes that have three dimensions – length, width, and height. Unlike two-dimensional shapes, three-dimensional shapes have thickness or depth.

A cube and cuboid are examples of three-dimensional objects, as they have length, width, and height.

• According to Albert Einstein Space and Time are the fourth dimension as he mentioned it in his book "Theory of Relativity
• Every three-dimensional figure houses many two-dimensional figures. We can by joining together many two-dimensional figures we get a three-dimensional figure.
