The value of the given number,

Solution,

Before solving the question, let's understand the concept of the cube number.

Cube number:- A cube number is what is produced when an integer is multiplied three times by itself. In its simplest form, a cube number is a product of three numbers.

It is written as 'b³.'

Now, let's solve the question,

45³ can be written as

= 45 × 45 × 45

= 91,125.

65³ can be written as

= 65 × 65 × 65

= 274,625

20³ can be written as

= 20 × 20 × 20

= 8,000

Now, we will subtract all the values to get the final value,

= 91,125 - 274,625 - 8000

= 91,125 - 282,625

On subtracting, we get

= -191,500.

The correct answer to the given question is -191,500.
