Work: Calculate the value of equation 1.2×1.5×40+0.7×2.1×19+0.7×1.5×3+1.5×1.5×4 .
Question type: Mathematical calculation
Solution:
1.2×1.5×40+0.7×2.1×19+0.7×1.5×3+1.5×1.5×4
=1.8×40+0.7×2.1×19+0.7×1.5×3+1.5×1.5×4
=72+0.7×2.1×19+0.7×1.5×3+1.5×1.5×4
=72+1.47×19+0.7×1.5×3+1.5×1.5×4
=72+27.93+0.7×1.5×3+1.5×1.5×4
=72+27.93+1.05×3+1.5×1.5×4
=72+27.93+3.15+1.5×1.5×4
=72+27.93+3.15+2.25×4
=72+27.93+3.15+9
=99.93+3.15+9
=103.08+9
=112.08
Answer:1.2×1.5×40+0.7×2.1×19+0.7×1.5×3+1.5×1.5×4=112.08
