Use two ways to get the number of small cubes to put these cubes in the cuboid.

The video tutorial explains how to calculate the number of small cubes that can fit into a cuboid by determining the volume of both the cuboid and the small cube. It provides two examples: one where the cuboid's dimensions are divisible by the cube's dimensions, allowing for straightforward calculation, and another where they are not, requiring a different approach. The tutorial emphasizes understanding divisibility to accurately determine the number of cubes that can fit inside a cuboid.

Why couldn't all the small pieces be placed inside the second cuboid?

What is the real number of small cubes that can fit in the second cuboid with dimensions 15, 11, and 8 centimeters?
