Answer 1

Answer:

import java.util.Scanner;

public class PaintCalc

{

public static void main(String[] args)

{

int length, width, height, numberOfDoors, numberOfWindows;

Scanner console = new Scanner(System.in);

System.out.print("Enter length: ");

length = console.nextInt();

System.out.print("Enter width: ");

width = console.nextInt();

System.out.print("Enter height: ");

height = console.nextInt();

System.out.print("Enter number of doors: ");

numberOfDoors = console.nextInt();

System.out.print("Enter number of windows: ");

numberOfWindows = console.nextInt();

int totalSurfaceArea = 2 * (length * width + length

* height + width * height);

int areaOfFloor = length * width;

int areaOfDoors = 20 * numberOfDoors;

int areaOfWindows = 15 * numberOfWindows;

int totalPaintArea = totalSurfaceArea - areaOfFloor

- areaOfDoors - areaOfWindows;

int requiredPaint = totalPaintArea / 350;

System.out.println("Paint required "

+ requiredPaint + " gallons.");
