    Use your motion formulae.

    Here, you make use of

    v = final velocity
    u = initial velocity
    a = acceleration
    s = displacement.

    Taking the upward direction as positive;
    u = +10m/s
    v = 0 m/s (when it reaches the max height, it is temporarily at rest)
    a = -9.81 m/s^2 (downward direction explaining the -ve sign)
    s = displacement (the one you're looking for)

    Solve for s, and you're done! :)

    I hope it helped! :)
