    Answer: (2) 7000

    Explanation:-
    x = 332, y = 333, z = 335
    Then, the value of x3 + y3 + z3 – 3xyz
    Put the value of x = 332, y = 333, z = 335
    Then,  = 3323 + 3333 + 3353 – 3 x 332 x 333 x 335
    = 36594368 + 36926037 + 37595375 + 111108780
    = 111115780 – 111108780
    = 7000

    Then, the value of x³+y³+z³-3xyz is 7000.
    Hence, the answer is (2) 7000.
