}

Ето това е едно примерно решение на Java :)

import java.util.Scanner;
public class Main
{
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        double w = Double.parseDouble(scanner.nextLine());
        double h = Double.parseDouble(scanner.nextLine());
        double wNoHall = h - 1;
        double deskOnRow = Math.floor(wNoHall / 0.7);
        double totalRows = Math.floor(w / 1.20);
        double totalPlaces = (deskOnRow * totalRows) - 3;
        
        System.out.println(totalPlaces);

    }
}
