Final answer:
The best estimate for the volume of a small carton of milk would be 250 milliliters, as it is comparable to the volume of a common juice box.
Step-by-step explanation:
The best estimate for the liquid volume of a small carton of milk would be 250 milliliters. This is because an eyedropper holds about 1 milliliter and a juice box holds about 250 milliliters (25 centiliters). A small carton of milk is similar in size to a juice box. When comparing volumes, remember that 1 liter is the same as 1000 milliliters. Therefore, when converting liters to milliliters, you multiply by 1000. Conversely, if you're converting milliliters to liters, you'd divide by 1000. For example, 2,000 milliliters would be converted to 2 liters (2,000 milliliters / 1,000 = 2 liters).
