Write a Python program that prompts the user to enter three values, each the length of the side of a particular square. Following the three input statements, there should be ONLY ONE MORE STATEMENT that prints the the number of square inches for the largest of the three square. Assume that there exists a value-returning function called max3 that returns the largest of three values passed to it. You do not need to write the function max3. Assume it exists and that you can use it.
