Paper Problem Solving Activity #9 - Fill warehouse with mud Imagine you are looking to rent a warehouse to hold a mud-wrestling party. Assuming warehouses are rectangles, with an elevated rectangular bar area above the mud, how could you calculate the cost to fill the warehouse with mud, except for the elevated bar area, assuming you know the width and length of the warehouse, the width and length of the bar area, and the preferred depth of mud. You know that mud costs $3 per cubic foot. Write a method to solve the problem. Make sure your method will work for any size warehouse, bar area and depth of mud. Your dimensions can be input from the console or as predefined variable values.
