    Answer:

    756

    Step-by-step explanation:

    As we know that,

    (x+y)³=x³+y³+3xy(x+y)……..(i)

    so we will write what’s given.

    we have,

    x+y=12 and xy=27

    Putting the values in equation (i), we get

    (12)³=x³+y³+3×27(12)

    1728=x³+y³+81(12)

    1728=x³+y³+972

    x³+y³=1728-972=756

    x³+y³=756
