Answer

  1. Since the ones place and tens place of 3600 is 0, the product must be a number with its hundreds place also 0 if it’s multiplied with another number.

    So the ones place of the number must be 0.


    The smallest number 23 is canceled.

    Then 60 multiplied with 3600 is equal to 216000, which is the perfect cube of 60
