Video Summary

Julio needs to construct a cross shape using various smaller pieces. The strategy is to optimize the assembly by focusing on efficiently covering the cross's corners. Instead of using a separate triangle and square for the edges, a diamond-shaped piece with an additional triangle is used, reducing the number of pieces from 3 to 2 for each section. By doing this for all ends and using basic pieces for the center, Julio can assemble the entire cross using only 13 pieces. Thus, the smallest number of pieces needed is 13.
