Answer:

hey

Explanation:

120 is not a perfect cube as

343 is the perfect cube of 7

125 is the perfect cube of 5

64 is the perfect cube of 4

but 120 on prime factorization gives 2 × 2 × 2 × 3 × 5. Here, the prime factor 3 is not in the power of 3. Therefore the cube root of 120 is irrational, hence 120 is not a perfect cube.

hope it helps
