Dimensions Definition

Generally, Dimension means direction. In Mathematics, Dimension is the measurement of a specific length in a particular direction. You can say that it is the measurement of any object, material, or length but in a particular direction.

For example, the measurement of the width, height, or depth of any shape or object.

General examples of Dimensions

In Mathematics, common factors help the student in solving different problems. Through common factors, you can find the LCM and HCF of the given numbers

  • A straight line.
  • Sides of a square
  • Lengths of a cube

Types of figures based on Dimensions

There are four major types of figures that we can discuss based on Dimensions.

  • Zero Dimensional: It is a particular figure that has arbitrary dimensions. For example, a “Dot” is an example of a zero-dimensional figure.
  • One Dimensional: It is a shape in Geometry that has only one direction. For example, a straight line is an example of this type of figure.

  • Two-Dimensional: This type of shape has two directions at a single connecting point. The simplest example of a two-dimensional figure is a square box.
  • Three-Dimensional: These are solid figures that have three directions at all connecting points. For example, your room is a three-dimensional figure because it has three directions at all corners of the room.


What is a three-dimensional square?

The three-dimensional square is also called a cube. The plane square is not a three-dimensional figure but it is a two-dimensional figure.

What do you mean by dimension?

Dimension means direction. In Mathematics, it means the measure of a length in a particular direction.

How many dimensions are in space?

In space, three dimensions are commonly used. In Advanced Physics, the number of dimensions increases in space.
