Solution

Prime factorising, we get,
106480=2×2×2×2×5×11×11×11

=(23×2×5×113)=(2×11)3×2×5
We know, a perfect cube has multiples of 3 as powers of prime factors.
In the above factorisation, 2 and 5 does not have their powers as multiple of 3.

Therefore, 106480 is not a perfect cube.
Hence, 0 is the answer.
