Find the cube of :
`-3`

Answer

To find the cube of -3, we follow these steps:

1. **Understand the concept of cubing a number**: The cube of a number \( x \) is calculated as \( x^3 \), which means multiplying the number by itself three times.

2. **Set up the multiplication**: For -3, we express it as:
\[ (-3)^3 = (-3) \times (-3) \times (-3) \]

3. **Multiply the first two terms**: Start by multiplying the first two -3's:
\[ (-3) \times (-3) = 9 \]
(Note: The product of two negative numbers is positive.)

4. **Multiply the result by the third -3**: Now take the result (9) and multiply it by the remaining -3:
\[ 9 \times (-3) = -27 \]
(Note: The product of a positive number and a negative number is negative.)

5. **Conclusion**: Therefore, the cube of -3 is:
\[ (-3)^3 = -27 \]
