How to Snap Together Cubes to Minimize Protruding Snaps?

How many snap-together cubes are needed to show only receptacle holes?

The smallest number of cubes needed is 28. But what is the arrangement to minimize protruding snaps?

Solution: Arranging the Snap-Together Cubes

To minimize protruding snaps and maximize receptacle holes, the cubes should be arranged in a 3x3x3 cube formation.

When arranging the snap-together cubes in a 3x3x3 cube formation, you will have 27 cubes initially. To eliminate all protruding snaps, one central cube must be removed, leaving 26 cubes. Each of the remaining cubes will have at least one side with receptacle holes facing outward, ensuring only receptacle holes are showing.

This arrangement ensures the smallest number of snap-together cubes needed to have only receptacle holes showing is 28. By following this specific arrangement, you can achieve the desired outcome while minimizing the exposure of protruding snaps.
