Answer:
Troy drinks 1,800 litres of water each day
Explanation:
The question is simply asking us to convert and unify the units between litres (L) and millilitres (mL).
amount of water drank = 1.8 L
1 litre = 1000 millilitre
1 L = 1000 mL
∴ 1.8 L = 1.8 × 1000 = 1,800
∴ Troy drinks 1,800 litres of water each day
