Answer: No
Explanation:
No, 648 is not a perfect cube because you need a number to be multiplied to 648 3 times and it equal 648.
EX. 8 is a perfect cube because 2*2*2 = 8 So the perfect cube of 8 =2
Nothing multiplies 3 times to = 648
8*8*8 = 512 >under 648
9*9*9 = 729 >over 648
So there is no number that multiplies 3 times to 648
