• (a^3-b^3)=(a-b)(a^2+ab+b^2+ab)
  a=40,b=36
  {(40*40*40)-(36*36*36)}=(40-36)(40^2+40*36+36^2)
  =4*(1600+1440+1296)

• (40*40*40)-(36*36*36)
  =(40-36)^3+3*40*36*(40-36)
  =4^3+3*40*36*4
  =64+17280

• as we know (a^3-b^3)=(a-b)(a^2+ab+b^2)
  a=40,b=36
  {(40*40*40)-(36*36*36)}=(40-36)(40^2+40*36+36^2)
  =4*(1600+1440+1296)
  =17344(ans)
