Question

The cube of an odd natural number is

• A. Even
• B. Odd
• C. May be even, May be odd
• D. Prime number

Answer 1

The correct option is B Odd

Odd natural numbers are not divided by 2

A number with cube means the number multiply itself three times

Multiplying odd number two times will give an odd number and then again multiplying with same number will give odd number.

So cube of odd number $3$ is $3\times 3\times 3=27$

And $5\times 5\times 5=125$

And $7\times 7\times 7=343$

All are odd natural numbers

Thus, cube of an odd natural number is odd.
