We Haven't Seen Any Math Questions in a While

To warm-up: Which 2-digit number is 1 more than a square and 1 less than a cube?

And a little bit harder: Can you find a three digit number which is 2 less than a cube and 2 more than a square?






Hint: the three digit number I can find is made of consecutive digits, like 567.

    Not bad for a Monday morning! ;-)

    26 is between 25 (5X5) and 27 (3X3X3)

    123 is two more than 121 (11X11) and two less than 125 (5X5X5)
