A solid cube is formed from 125 unit cubes. A set of smaller unit cubes will be removed, leaving behind a smaller solid cube. In how many ways can this be done?
Not sure what the question is asking bu you could take away 124, 117, 98 or 61 little cubes.
1^3=1 125-1=124
2^3=8 125-8=117
3^3=27 125-27=98
4^3=64 125-64 =61
5^3=125
