Hi
Am having a complete mental block this afternoon! Can anyone explain the answer to the following question for me please?

Which answer has three numbers that are all cube numbers?
8 16 32
8 27 64
16 32 64
9 27 64
5 25 125

DD has put 16 32 64 as her answer & is convinced that is correct but the answer should be 8 27 64.

Thanks in advance
Ann

2*2*2=8
3*3*3=27
4*4*4=64
