    std::cin >> k;

    int soLuongKhoi = (n * (n + 1) * (2 * n + 1)) / 6;

    int soTangToiDa = 0;

    while (k >= soLuongKhoi) {

        soTangToiDa++;

        k -= soLuongKhoi;

        n++;

        soLuongKhoi = (n * (n + 1) * (2 * n + 1)) / 6;

    }

    std::cout << "a) So luong khoi lap phuong Be An da dung de xep duoc thap co chieu cao " << n << " tang: " << soTangToiDa << std::endl;
