1. The problem shows a measuring cup with water level between 2 liters and 3 liters, closer to 3 liters. 2. We need to estimate the water volume based on the position between the marks. 3. Since the water is closer to 3 liters than 2 liters, it is more than halfway between 2 and 3 liters. 4. If halfway is 2.5 liters, and the water is closer to 3 liters, a reasonable estimate is about 2.8 liters. 5. Therefore, the water volume is approximately $2.8$ liters.
