Question 1189335
<br>
Since the problem asks for the APPROXIMATE capacity, you can round the numbers to get numbers that are easier to work with.  Then of course you need to convert the result in ml to liters.<br>
You are multiplying two numbers; to get a good approximation, you want to round one number up a bit and the other down a bit.  That is convenient with the given numbers -- round the 290ml up to 300ml, and round the 63 cups down to 60 cups. Then<br>
(60 cups) * (300ml/cup) = 18000ml = 18 liters<br>
ANSWER: approximately 18 liters<br>
