Density

Real World Example

Imagine trying to pack a suitcase for a trip, and finding it difficult to fit everything in. This challenge is similar to the concept of density, where you need to fit as much mass (clothes) as possible into a limited volume (the suitcase). Just like a denser object has more mass in a given space, a well-packed suitcase holds more items in the same amount of space, showing how efficiently you can use the volume available.
