Let 0.2 =a
- 0.3 =b
0.1=c
Here a+b+c =0
Therefore, a cube + b cube + c cube = 3(a into b into c)
Therefore 0.2 cube + (-0.3) cube + 0.1 cube =3(0.2 into - 0.3 into 0.1)=-0.018
- 0.3 =b
0.1=c
Here a+b+c =0
Therefore, a cube + b cube + c cube = 3(a into b into c)
Therefore 0.2 cube + (-0.3) cube + 0.1 cube =3(0.2 into - 0.3 into 0.1)=-0.018
