Final answer:
To calculate the total volume of water in milliliters, convert the liters to milliliters. Sasha drinks 2500 milliliters each weekday and 3000 milliliters on the weekend, resulting in a total volume of 5500 milliliters.
Step-by-step explanation:
Sasha drinks 2.5 liters each weekday and 3 liters of water on the weekend. To calculate the total volume of water in milliliters, we first need to convert the liters to milliliters. One liter is equal to 1000 milliliters, so 2.5 liters is equal to 2.5 x 1000 = 2500 milliliters. Thus, Sasha drinks 2500 milliliters of water each weekday. On the weekend, 3 liters is equal to 3 x 1000 = 3000 milliliters. Therefore, the total volume of water in milliliters is 2500 + 3000 = 5500 milliliters.
