Cube Roots and Prime Factorization

The video tutorial explains how to find the cube root of 216 using a factor tree. It begins by breaking down 216 into its prime factors, which are three 2s and three 3s. The tutorial then demonstrates how to use these prime factors to calculate the cube root by grouping them in threes and taking one number from each group. The result is that the cube root of 216 is 6. The video concludes with a motivational message about kindness.
