Video Summary

Masuda and his friends built a structure using 66 cubes to form the number 2022, and painted the surface yellow. The task is to determine how many cubes have exactly four faces painted. Cubes connected to two others have four painted faces, while those connected to only one cube have five painted faces. The number comprises digits 2 and 0. In the digit zero, all cubes have four painted faces. In the digit two, six cubes have five painted faces. Therefore, subtracting these from the total, 60 cubes have exactly four faces painted. The answer is 60 cubes.
