Answer 1

The largest 3 digits number is 999 which is not the perfect cube.

So, nearest number which is perfect is 1000 nd cube root is 10. But the number is of 4 digits.

So, the required cube root less than 10.

So, try to find one by one.......

Cube of 6 = 216 ; sum of digits is 9 which is perfect square.
