1. The first screenshot shows a 6 by 6 grid of cubes, so the total number of blocks is calculated as $$6 \times 6 = 36$$. 2. The second screenshot shows a grid of 27 cubes arranged in 5 rows and 6 columns (with the last row partially empty). Since it is explicitly stated as 27 cubes, the total number of blocks is $$27$$. 3. The third screenshot shows a 6 by 6 grid of cubes, so the total number of blocks is $$6 \times 6 = 36$$. 4. The fourth screenshot shows a grid of 36 squares in 6 rows and 6 columns, so the total number of blocks is $$6 \times 6 = 36$$. 5. To find the final total number of blocks from all screenshots, sum the totals: $$36 + 27 + 36 + 36 = 135$$ Therefore, the final total number of blocks from all screenshots combined is **135**.
