a 3 cm by 3 cm by 3 cm cube is painted all over its outside and is then cut into 27 smaller cubes. How many of these small cubes have paint on more than one face? please explain how you work it out,thanks

  • math -

    any of the smaller cubes on the outside faces and edges will have paint on them
    The only ones without any paint will be the single small cube in the middle. So one of them
