1. The problem asks us how many liters of water are needed to fill a fishbowl with a capacity of 5600 cubic centimeters (cc). 2. We know that 1 liter (L) is equal to 1000 cubic centimeters (cc). 3. To convert from cubic centimeters to liters, divide the volume in cc by 1000: $$\text{Volume in liters} = \frac{5600}{1000} = 5.6$$ 4. Therefore, 5.6 liters of water are needed to fill the fishbowl. 5. The correct answer is b. 5.6 L.
