Work: Calculate the value of equation ((1.6+1.6)×2×0.5+(2.8+2.8)×2×0.5+(4+4)×2×0.5)×12+((1.6+4.3)×2×0.5+(2.8+5.4)×2×0.5+(4+6.5)×2×0.5)×7 .
Question type: Mathematical calculation
Solution:
((1.6+1.6)×2×0.5+(2.8+2.8)×2×0.5+(4+4)×2×0.5)×12+((1.6+4.3)×2×0.5+(2.8+5.4)×2×0.5+(4+6.5)×2×0.5)×7
=(3.2×2×0.5+(2.8+2.8)×2×0.5+(4+4)×2×0.5)×12+((1.6+4.3)×2×0.5+(2.8+5.4)×2×0.5+(4+6.5)×2×0.5)×7
=(3.2×2×0.5+5.6×2×0.5+(4+4)×2×0.5)×12+((1.6+4.3)×2×0.5+(2.8+5.4)×2×0.5+(4+6.5)×2×0.5)×7
=(3.2×2×0.5+5.6×2×0.5+8×2×0.5)×12+((1.6+4.3)×2×0.5+(2.8+5.4)×2×0.5+(4+6.5)×2×0.5)×7
=16.8×12+((1.6+4.3)×2×0.5+(2.8+5.4)×2×0.5+(4+6.5)×2×0.5)×7
=16.8×12+(5.9×2×0.5+(2.8+5.4)×2×0.5+(4+6.5)×2×0.5)×7
=16.8×12+(5.9×2×0.5+8.2×2×0.5+(4+6.5)×2×0.5)×7
=16.8×12+(5.9×2×0.5+8.2×2×0.5+10.5×2×0.5)×7
=16.8×12+24.6×7
=201.6+24.6×7
=201.6+172.2
=373.8
Answer:((1.6+1.6)×2×0.5+(2.8+2.8)×2×0.5+(4+4)×2×0.5)×12+((1.6+4.3)×2×0.5+(2.8+5.4)×2×0.5+(4+6.5)×2×0.5)×7=373.8
