[1/1 Formula]
    Work: Calculate the value of equation (1.6×1.6×0.5+2.8×2.8×0.5+4×4×0.5)×12+(1.6×4.3×0.5+2.8×5.4×0.5+4×6.5×0.5)×7 .
    Question type: Mathematical calculation
    Solution:
          (1.6×1.6×0.5+2.8×2.8×0.5+4×4×0.5)×12+(1.6×4.3×0.5+2.8×5.4×0.5+4×6.5×0.5)×7
        =13.2×12+(1.6×4.3×0.5+2.8×5.4×0.5+4×6.5×0.5)×7
        =13.2×12+24×7
        =158.4+24×7
        =158.4+168
        =326.4

    Answer:(1.6×1.6×0.5+2.8×2.8×0.5+4×4×0.5)×12+(1.6×4.3×0.5+2.8×5.4×0.5+4×6.5×0.5)×7=326.4
