[1/1 Formula]
    Work: Calculate the value of equation 0.7×2.1×353+1.2×2.1×20+1.8×2.1×68 .
    Question type: Mathematical calculation
    Solution:
          0.7×2.1×353+1.2×2.1×20+1.8×2.1×68
        =1.47×353+1.2×2.1×20+1.8×2.1×68
        =518.91+1.2×2.1×20+1.8×2.1×68
        =518.91+2.52×20+1.8×2.1×68
        =518.91+50.4+1.8×2.1×68
        =518.91+50.4+3.78×68
        =518.91+50.4+257.04
        =569.31+257.04
        =826.35

    Answer:0.7×2.1×353+1.2×2.1×20+1.8×2.1×68=826.35
