    题型：数学计算
    解:
          155×(4.688+3.688+4.088+3.488)+1/2×52.7×3.188×5.1+1/2×52.7×8.5×3.188
        =155×15.952+1/2×52.7×3.188×5.1+1/2×52.7×8.5×3.188
        =2472.56+1/2×52.7×3.188×5.1+1/2×52.7×8.5×3.188
        =2472.56+0.5×52.7×3.188×5.1+1/2×52.7×8.5×3.188
        =2472.56+26.35×3.188×5.1+1/2×52.7×8.5×3.188
        =2472.56+84.0038×5.1+1/2×52.7×8.5×3.188
        =2472.56+428.41938+1/2×52.7×8.5×3.188
        =2472.56+428.41938+0.5×52.7×8.5×3.188
        =2472.56+428.41938+26.35×8.5×3.188
        =2472.56+428.41938+223.975×3.188
        =2472.56+428.41938+714.0323
        =2900.97938+714.0323
        =3615.01168
    答案:155×(4.688+3.688+4.088+3.488)+1/2×52.7×3.188×5.1+1/2×52.7×8.5×3.188=3615.01168
