Answer:
One liter is equivalent to 4 cups, so 3 1/2 cups is less than 1 liter. To show this, we can convert both quantities to a common unit of measurement, such as milliliters. One liter is equal to 1000 milliliters, and 3 1/2 cups is equal to about 840 milliliters. Since 840 milliliters is less than 1000 milliliters, 3 1/2 cups is also less than 1 liter.
