        =11.242*95.142+18.563*2.2*2+37.6982*0.1+4.542*0.3+24.07*2*2
        =1069.586364+18.563*2.2*2+37.6982*0.1+4.542*0.3+24.07*2*2
        =1069.586364+40.8386*2+37.6982*0.1+4.542*0.3+24.07*2*2
        =1069.586364+81.6772+37.6982*0.1+4.542*0.3+24.07*2*2
        =1069.586364+81.6772+3.76982+4.542*0.3+24.07*2*2
        =1069.586364+81.6772+3.76982+1.3626+24.07*2*2
        =1069.586364+81.6772+3.76982+1.3626+48.14*2
        =1069.586364+81.6772+3.76982+1.3626+96.28
        =1151.263564+3.76982+1.3626+96.28
        =1155.033384+1.3626+96.28
        =1156.395984+96.28
        =1252.675984
    答案:(8.2+0.3*2+1.221*2)*(92.1+0.3*2+1.221*2)+(15.521+0.3*2+1.221*2)*2.2*2+(36.233+0.3*2*1.221*2)*0.1+(1.5+0.3*2+1.221*2)*0.3+(21.028+0.3*2+1.221*2)*2*2=1252.675984
