Best Description

A 5 cm side length cube is painted on all sides and then cut into 1 cm³ smaller cubes. To find the number of smaller cubes with exactly one painted face, we consider the center cubes on each face of the larger cube. Each face has a 3x3 grid of such cubes (excluding edge and corner cubes), totaling 9 per face. With 6 faces, the total number of 1 cm³ cubes with exactly one painted side is 6×9=54.
