    Question type: Mathematical calculation
    Solution:
          (20+18.5×1.525+19.8×43.8+19.4×1.8)×0.61-2×29×√0.61
        =950.3725×0.61-2×29×√0.61
        =950.3725×0.61-2×29×0.781025
        =579.727225-2×29×0.781025
        =579.727225-58×0.781025
        =579.727225-45.29945
        =534.427775
