Assume that a gallon of paint covers about 350 square feet of wall space. Create an application with a main() method that prompts the user for the length, width, and height of a rectangular room. Pass these three values to a method that does the following:
1. Calculates the wall area of a room2. Passes the calculated wall area to another method that calculates and returns thenumber of gallons of paint needed.3. Displays the number of gallons needed.4. Computes the price based on a paint price of $32 per gallon, assuming that the paintercan buy any fraction of a gallon of paint at the same price as a whole gallon.5. Returns the price to the main() method.
The main() method displays the final price. For example, the cost to paint a 15- by-20-foot room with 10-foot ceilings is $64. Save the application as Paint Calculator. java.
