    Answer:

    3

    Step-by-step explanation:

    64 is the nearest cube to the 72.

    let us factorize the 72

    2|72

    2|36

    2|18

    3|9

    3|3

    |1

    Now, make pairs 2×2×2 will be 2

    and 3×3 is not a perfect cube so we will multiply this number by 3

    72×3=216 , which is cube root of 6.

    Hence, answer is 3.
