Answer:
15000 millilitres
Explanation:
A large cooler contains 20 liters of iced tea and a small cooler contains 5 liters of iced tea.
To find the amount of iced tea the large cooler contains more than the small cooler, we simply need to subtract the amount of iced tea in the small cooler from the large cooler and then, convert it to millilitres.
That is:
20 - 5 = 15 litres
Converting 15 litres to millilitres:
1 litre = 1000 millilitres
=> 15 litres = 15 * 1000 = 15000 millilitres
The large cooler contains 15000 more millilitres than the small cooler.
