(a + b)3 = a3 + b3 + 3ab(a +b)

(10)3 = a3 + b3 + 3*16(10)

1000 = a3 + b3 + 480

a3 + b3 = 1000 -480 = 520

a3 +b3 = ( a+  b) (a2 - ab + b2)

520 = 10(a2 - ab +b2)

a2 - ab + b2 = 520 / 10 = 52

if we see 8 + 2 = 10 , 8 * 2 = 16

a - b = 8 - 2 = 6

(8)2 + (2)2 + 16 = 64 + 16 + 4 = 64 +20 = 84 = a2 + ab + b2

therefore,a2 - ab + b2 =52
and a2 + ab + b2=84
I hoep this helps.
