Answer:
11,355 mL
Explanation:
This problem gives you too much information just to confuse you, but you can ignore it.
There are 3,785 mL in 1 gallon.
How many mL are there in 3 gallons?
(The statement about 4 quarts in 1 gallon is not necessary, so just ignore it.)
If 1 gal has 3,785 mL, then 3 gallons has 3 times as many mL.
1 gal = 3,785 mL
3 × 1 gal = 3 × 3,785 mL
3 gal = 11,355 mL
Answer: 11,355 mL
