space. Create an application with a main() method that prompts
4
the user for the length, width, and height of a rectangular room.
}
</>
Pass these three values to a method that does the following:
6
public static double computeArea(double length, double width, double height) {
// Write your code here
7
8
• Calculates the wall area for a room
}
public static double computeGallons(double area) {
// Write your code here
9
• Passes the calculated wall area to another method that
10
11
calculates and returns the number of gallons of paint needed
12
}
• Displays the number of gallons needed
13 }
• Computes the price based on a paint price of $32 per gallon,
assuming that the painter can buy any fraction of a gallon of
paint at the same price as a whole gallon
• Returns the price to the main() method
The main() method displays the final price. For example:
You will need 2.0 gallons
The price to paint the room is $64.0
