Final answer:
A 1,800 cm³ pan can hold 1.8 liters of water, following the conversion that 1 cm³ is equivalent to 1 mL, and 1 L is equal to 1,000 cm³.
Step-by-step explanation:
One cubic centimeter (cm³) is equal to one milliliter (mL), which tells us about the interrelationship between volume units in the metric system. Since a liter (L) is defined as equivalent to one thousand cubic centimeters (1,000 cm³), to determine how many liters of water a 1,800 cm³ pan can hold, we divide the volume of the pan by the volume of a liter in cubic centimeters.
1,800 cm³ / 1,000 cm³/L = 1.8 L
Therefore, a 1,800 cm³ pan can hold 1.8 liters of water.
