Answer: The number must be between 45 and 158.
To find the whole number that has a square between 2000 and 25000, we need to determine the square root of the given limits.
The square root of 2000 is approximately 44.72, and the square root of 25000 is approximately 158.11.
Since the square of a whole number falls between the squares of these two square roots, the whole number must be between the smallest whole number greater than the smaller square root and the largest whole number smaller than the larger square root.
So, the whole number must be between 45 and 158.
