Capacity of 1 bottle = 200 mL
∴ Capacity of 15 such bottles
=
200×15
= 3000 mL
∴ Capacity of the carton = 3000 mL
We need to convert this capacity to liters.
Let us look at the conversion chart given below.
To move from a smaller unit to a larger unit right above it, we divide by 10.
To convert milliliters to liters, we need to move three units up. Thus, we divide by 10 thrice, i.e., 1000.
∴1 mL=11000 L
∴3000 mL=30001000=3 L
Thus, the capacity of the carton is 3 L.
