Answer 2

Answer:

The cube of -1.1 is -1.331.

Step-by-step explanation:  

Cube of a number:

• When a number is multiplied three times by itself, the product obtained is called the cube of a number.
• For a given number $x$, the cube of x is $x \times x \times x= x^3$.

Given the number -1.1.

Multiplying -1.1 thrice with -1.1, we get the cube of -1.1.

$(-1.1)^3=(-1.1) \times (-1.1) \times (-1.1)$

Applying the rules of multiplication of integers,

1. product of negative and negative integer is a positive integer.
2. product of negative and positive integer is a negative integer.

$(-1.1) \times (-1.1) \times (-1.1)$

$=1.21\times (-1.1)$

$=-1.331$

Therefore, the cube of -1.1 is -1.331.
