## Some important Facts

- Numbers like 1729, 4104, 13832, are known as Hardy – Ramanujan Numbers. They can be expressed as sum of two cubes in two different ways.
- Numbers obtained when a number is multiplied by itself three times are known as
**cube numbers**. For example 1, 8, 27, … etc. - If in the prime factorisation of any number each factor appears three times, then the number is a perfect cube.
- The symbol root 3 denotes cube root. For example cube root of 27 is 3.

## Cube Roots

If the volume of a cube is 125 cm3, what would be the length of its side? To get the length of the side of the cube, we need to know a number whose cube is 125. Finding the square root, as you know, is the inverse operation of squaring. Similarly, finding the cube root is the inverse operation of finding cube.

**State true or false.**

- Cube of any odd number is even.
- A perfect cube does not end with two zeros.
- If square of a number ends with 5, then its cube ends with 25.
- There is no perfect cube which ends with 8.
- The cube of a two digit number may be a three digit number.
- The cube of a two digit number may have seven or more digits.
- The cube of a single digit number may be a single digit number
