@tbeneka 
can you explain what it is asking?

anonymous · Answer

I'm thinking it is asking which one is a perfect cube. 

I think this because the formula for the volume of a cube is  $$V=a ^{3}$$

and an integer is a number that is not a decimal.. So the only way this word work is if one of the volumes is a perfect cube
