Understanding the Tower of Cubes

The video tutorial explains how to determine the total number of cubes in a tower when given that twelve cubes represent two-thirds of the tower's height. It breaks down the problem by explaining the concept of two-thirds, dividing the twelve cubes into two equal parts to find one-third of the height, and then calculating the total number of cubes by multiplying one-third by three. The solution is illustrated step-by-step to ensure understanding.

If twelve cubes represent two-thirds of a tower's height, how many cubes make up the entire tower?

• Eighteen cubes

• Six cubes

• Twenty-four cubes

• Thirty cubes
