The interval of interest is \( (12.56, 31.4) \). We seek the whole numbers strictly greater than 12.56 and strictly less than 31.4. These numbers are:
["Interval of Interest: Whole Numbers Between 12.56 and 31.4", "When working with intervals in mathematics, one of the most useful tasks is identifying all whole numbers that lie strictly between two given values.
