Work: Calculate the value of equation (20%*(50%-18%)^3+30%*(25%-18%)^3+30%*(15%-18%)^3+20%*(-20%-18%)^3)/(0.226053)^3 .
Question type: Mathematical calculation
Solution:
(20%*(50%-18%)^3+30%*(25%-18%)^3+30%*(15%-18%)^3+20%*(-20%-18%)^3)/(0.226053)^3
=(20%*0.32^3+30%*(25%-18%)^3+30%*(15%-18%)^3+20%*(-20%-18%)^3)/(0.226053)^3
=(20%*0.32^3+30%*0.07^3+30%*(15%-18%)^3+20%*(-20%-18%)^3)/(0.226053)^3
=(20%*0.32^3+30%*0.07^3+30%*(-0.03)^3+20%*(-20%-18%)^3)/(0.226053)^3
=(20%*0.32^3+30%*0.07^3+30%*(-0.03)^3+20%*(-0.38)^3)/(0.226053)^3
=-0.004325/(0.226053)^3
=-0.004325/0.226053^3
=-0.004325/0.011551298988651
=-0.374417
Answer:(20%*(50%-18%)^3+30%*(25%-18%)^3+30%*(15%-18%)^3+20%*(-20%-18%)^3)/(0.226053)^3=-0.374417
