    Step-by-step explanation:

    y varies directly as the cube of x:

    this means y is proportional to the cube of x

    y α x^3

    or

    y = cx^3

    Where 'c' is some constant.

    plug in the given x and y and solve for c, then you can plug in c and the new x and solve for y.

    Give it a shot and come back with a question and your attempt at solving this problem if you're still confused.
