    题型：数学计算
    解:
          155×(0.875+0.795+0.715+0.635)+1/2×52.7×1.7×0.085+1/2×52.7×0.595×11.9
        =155×3.02+1/2×52.7×1.7×0.085+1/2×52.7×0.595×11.9
        =468.1+1/2×52.7×1.7×0.085+1/2×52.7×0.595×11.9
        =468.1+0.5×52.7×1.7×0.085+1/2×52.7×0.595×11.9
        =468.1+26.35×1.7×0.085+1/2×52.7×0.595×11.9
        =468.1+44.795×0.085+1/2×52.7×0.595×11.9
        =468.1+3.807575+1/2×52.7×0.595×11.9
        =468.1+3.807575+0.5×52.7×0.595×11.9
        =468.1+3.807575+26.35×0.595×11.9
        =468.1+3.807575+15.67825×11.9
        =468.1+3.807575+186.571175
        =471.907575+186.571175
        =658.47875
    答案:155×(0.875+0.795+0.715+0.635)+1/2×52.7×1.7×0.085+1/2×52.7×0.595×11.9=658.47875
