Example 14: Amit bought 8 cold drink bottles. Each bottle contained 2
L 250 mL. How much quantity of cold drink did he buy?

Solution: Cold drink in one bottle = 2 L 250 mL

Cold drink in 8 bottles
2 2 5 0
= 2 L 250 mL × 8
× 8
= 2250 mL × 8
1 8 0 0 0 mL = 18 L
= 18000 mL = 18 L

Thus, Amit bought 18 L cold drink.
