What Is the Most Efficient Way to Stack Coins?

Imagine you have a bunch of coins, like quarters. If you just put one on top of another, they’re not going to last long, it’s like building a tower with blocks that can’t hold up. But if you tilt them so the sides touch each other, like the corners of squares touching in a pattern, they actually balance better! This is called coin stacking, and it helps make the stack more stable and efficient.
