Let's analyze the given information:
- The top face has 8 cubes in a 4x2 arrangement, with the pattern starting with a light-colored square.
- The front face has 12 cubes in a 4x3 arrangement, with the pattern starting with a light-colored square.
- The right face has 6 cubes in a 3x2 arrangement, with the pattern starting with a light-colored square.
Since the corner cubes are black, we know that the corner cubes of the large cube are black. Therefore, the top right corner cube, the front right corner cube, and the top front corner cube are black.
From the information given, we can deduce that the top face has 4 black cubes, the front face has 6 black cubes, and the right face has 3 …

There are 8 corner cubes, so there are non-corner cubes. Each non-corner cube has two possible orientations, and half of these orientations have black on the top face (which is what we're trying to maximize). So there are ways to orient the non-corner cubes, and of them will have black on the top face.
