Correct Answer: 64


Solution : Let's check the options –
First option: 8; 8 = 2 3 (2 is a prime number.)
Second option: 64; 64 = 4 3 (4 is not a prime number.)
Third option: 125; 125 = 5 3 (5 is a prime number.)
Fourth option: 343; 343 = 7 3 (7 is a prime number.)

So, only the number in the second option is not the cube of a prime number. Hence, the second option is correct.
