    Predict what the water level in units will be on the left side. Typical Solutions. Someone with knowledge about the area of triangles might reason: "Initially the area of the water forming the triangle is 12 since ⁠ 1 / 2 ⁠ × 4 × 6 = 12. The amount of water doesn't change so the area won't change. So the answer is 3 because ⁠ 1 / 2 ...
