## Cube Numbers

First Column represents Natural Number and Second column represents cube numbers of respective Natural Numbers

Natural Numbers 8, 27, 64, 125 and 216 all are examples of cube numbers.

** Cube Numbers are also known as Perfect Cubes **

Properties of Cube Numbers

Before you read What is a perfect cube, you are advised to read:

What are Natural Numbers ?

What are Exponents ?

When a Natural Number X can be expressed as Y^{3} (here Y is also a Natural Number), then the Natural Number X is referred to as ** Cube Number ** of Natural Number Y.

e.g. 125 can be expressed as 5^{3}

In this example:

125 is a Natural Number X

5 is a Natural Number Y

125 = Y^{3}

Therefore, 125 is referred to as cube number of natural number 5

Or we can also say that:

When a natural number is multiplied thrice by itself, the resultant number is known as cube of the given natural number

e.g. 9 when multiplied thrice by itself, we get:

9 X 9 X 9 = 729

Therefore, 929 is a cube of 9

Study the following table

Natural Number | Cube Number |
---|---|

2 | 8 |

3 | 27 |

4 | 64 |

5 | 125 |

6 | 216 |
