    Answer:

    3025

    Step-by-step explanation:

    The formula for finding the sum of cubes of ‘n’ numbers is

    (\frac{n(n +1)}{2} )^{2}

    Here n = 10.

    Therefore, the sum is

    (\frac{10(10 + 1)}{2}) ^{2} =(\frac{10*11}{2}) ^{2} = (5*11)^{2} =55^{2}

    55^{2} = 3025

    Hope this helps.
