Cube Numbers

The video tutorial explains how to count the number of cube-shaped blocks in a structure by dividing it into layers. Each layer consists of 4 rows and 4 columns, totaling 16 blocks per layer. The total number of blocks is calculated as 4 times 16, equaling 64, which is a cube number. The concept of cube numbers is introduced, defined as a positive integer multiplied by itself twice. The video also presents the first five cube numbers, drawing a parallel to square numbers.
