Work: Calculate the value of equation 450×12×(116.17-0.5×12)+2×(116.17-12)×12×0.5×(116.17-12) .
Question type: Mathematical calculation
Solution:
450×12×(116.17-0.5×12)+2×(116.17-12)×12×0.5×(116.17-12)
=450×12×110.17+2×(116.17-12)×12×0.5×(116.17-12)
=450×12×110.17+2×104.17×12×0.5×(116.17-12)
=450×12×110.17+2×104.17×12×0.5×104.17
=5400×110.17+2×104.17×12×0.5×104.17
=594918+2×104.17×12×0.5×104.17
=594918+208.34×12×0.5×104.17
=594918+2500.08×0.5×104.17
=594918+1250.04×104.17
=594918+130216.6668
=725134.6668
Answer:450×12×(116.17-0.5×12)+2×(116.17-12)×12×0.5×(116.17-12)=725134.6668
