    To find the cube root of a number is a bit more complicated and in our days is considered impractical, but here is a method explained. Look at the 2nd example scrolling down about 1/3 of the page

    If you want to know the concept of square roots and cube roots ?
    the square root of a number is that number which when multiplied by itself two times gives us that number
    e.g.
    √64 = x , so that (x)(x) = 64
    and from our multiplication table we know that
    (8)(8) = 64 , so that
    √64 = 8

    the cube root of a number is that number which when multiplied by itself three times gives us that number
    e.g.
    ∛64 = x , so that (x)(x)(x) = 64 , and thus x = 4 because 4x4x4 = 64
    so ∛64 = 4
