The cube root of 216 is 6. This means that 6 multiplied by itself three times gives the product of 216. One way to find the cube root of 216 is by using the prime factorization method. The prime factorization of 216 is 2 x 2 x 2 x 3 x 3 x 3. Grouping three identical factors in one group, we have two groups of 2 and one group of 3. Taking one number from each group, we get 2 x 3 = 6. Therefore, the cube root of 216 is 6.
