Question

Assume that a gallon of paint covers about 350 square feet of wall space. Create a class called PaintCalculator with a main() method that prompts the user for the length, width, and height of a rectangular room, all three of type double. Pass these three values to a method called computeArea() that does the following:

Calculates the wall area for a room
Passes the calculated wall area to another method called computeGallons() that calculates and returns the number of gallons of paint needed
Displays the number of gallons needed
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, the cost to paint a 15-by-20-foot room with 10-foot ceilings is $64.

An example of the program is shown below;

Enter the room's length >> 13.2 Enter the room's width >> 10.5 Enter the room's height >> 9.0 You will need 1.2188571428571429 gallons The price to paint the room is $39.00342857142857

info> In order to complete the computeArea() method, you first need to implement the computeGallons() method.

Task 01: Create the PaintCalculator class.

Task 02: The computeGallons() method returns the gallons needed for an area.

Task 03: The computeArea() method returns the price needed to paint a room.

Task 04: The PaintCalculator program displays the number of gallons and the cost to paint a room.
