[1/1 Formula]
Work: Calculate the value of equation 1/12×(0.45)^2×((2×1.8+1.8)*(381.9+349.9-(2×1.35×0.8×26)/(1.8×1.8))+(381.9-349.9)×1.8) .
Question type: Mathematical calculation
Solution:
1/12×(0.45)^2×((2×1.8+1.8)*(381.9+349.9-(2×1.35×0.8×26)/(1.8×1.8))+(381.9-349.9)×1.8)
=1/12×0.45^2×((2×1.8+1.8)*(381.9+349.9-(2×1.35×0.8×26)/(1.8×1.8))+(381.9-349.9)×1.8)
=1/12×0.45^2×(5.4*(381.9+349.9-(2×1.35×0.8×26)/(1.8×1.8))+(381.9-349.9)×1.8)
=1/12×0.45^2×(5.4*(381.9+349.9-56.16/(1.8×1.8))+(381.9-349.9)×1.8)
=1/12×0.45^2×(5.4*(381.9+349.9-56.16/3.24)+(381.9-349.9)×1.8)
=1/12×0.45^2×(5.4*714.466667+(381.9-349.9)×1.8)
=1/12×0.45^2×(5.4*714.466667+32×1.8)
=1/12×0.45^2×3915.720002
=1/12×0.2025×3915.720002
=0.083333×0.2025×3915.720002
=0.016875×3915.720002
=66.077775
Answer:1/12×(0.45)^2×((2×1.8+1.8)*(381.9+349.9-(2×1.35×0.8×26)/(1.8×1.8))+(381.9-349.9)×1.8)=66.077775
