2×19.3×0.84×2.7+2×3×43.49×1.5+2×2.45×0.84×1.2+300×0.6×3×2.7
=38.6×0.84×2.7+2×3×43.49×1.5+2×2.45×0.84×1.2+300×0.6×3×2.7
=32.424×2.7+2×3×43.49×1.5+2×2.45×0.84×1.2+300×0.6×3×2.7
=87.5448+2×3×43.49×1.5+2×2.45×0.84×1.2+300×0.6×3×2.7
=87.5448+6×43.49×1.5+2×2.45×0.84×1.2+300×0.6×3×2.7
=87.5448+260.94×1.5+2×2.45×0.84×1.2+300×0.6×3×2.7
=87.5448+391.41+2×2.45×0.84×1.2+300×0.6×3×2.7
=87.5448+391.41+4.9×0.84×1.2+300×0.6×3×2.7
=87.5448+391.41+4.116×1.2+300×0.6×3×2.7
=87.5448+391.41+4.9392+300×0.6×3×2.7
=87.5448+391.41+4.9392+180×3×2.7
=87.5448+391.41+4.9392+540×2.7
=87.5448+391.41+4.9392+1458
=478.9548+4.9392+1458
=483.894+1458
=1941.894
Answer:2×19.3×0.84×2.7+2×3×43.49×1.5+2×2.45×0.84×1.2+300×0.6×3×2.7=1941.894
