I failed by misreading the problem on this one. I thought the sonar beam grid was of size 4 instead of size 3. It cost me two WA’s :(

import java.util.Scanner;

    Scanner sc = new Scanner(System.in);

    int N = Integer.parseInt(sc.nextLine());

      int X = sc.nextInt();
      int Y = sc.nextInt();
      out.println((long) (Math.ceil((X - 2) * 1.0 / 3) * Math.ceil((Y - 2) * 1.0 / 3)));
      N--;
    }
    out.close();
    sc.close();
