Lesson: 12: Whole Numbers
Topic: Cubes and Cube Roots
Domain: Number

Cubing multiplies a number by itself three times, filling a solid cube. A cube root undoes it, and prime factors are grouped in threes rather than pairs.

Study Tip

Learn the ten cube numbers and the last digit trick. Every digit appears exactly once as the last digit of a cube, so it names the last digit of the root with certainty.
