Question

Smallest 5 digit perfect cube number

Answer 1

10,648 is the smallest 5-digit perfect cube

Since, 21 x21 x 21 = 9261 ( highest 4- digit cube)

Next is 22 x 22 x 22 = 10648

Answer 2

The smallest 5 digit number = 10000

10000 is not the perfect cube.

Let us take some Numbers to obtain perfect cube



20³ = 8000 it is less than smallest 5-digit number

21³= 9261 it is the largest 4 digit perfect cube.

So,

22³ = 10648 it is the smallest 5-digit perfect cube.


Hence, we can observe that 10648 is the smallest 5-digit perfect cube.
