There are 4 quarts in 1 gallon. This means that you would need to fill up a quart container 4 times and you would have a gallon.
Since there are 10 quarts in this problem, you could create two full gallons (because 2 * 4 = 8). Then you would have 2 quarts left over. Also, these 2 quarts would be equivalent to a half- gallon.
