Add square tiles to the 12-by-12 grid so that the total points in each row and each column matches the corresponding value outside the grid.

• A tile can have any side length (e.g., 1-by-1, 2-by-2, 3-by-3, etc.)
• Every cell within an n-by-n tile is worth n points.
• Tiles may not overlap. Not every cell in the 12-by-12 grid needs to be inside one of the tiles.
• For your answer, submit the product of the areas of each contiguous empty space in the solved grid.
