To calculate the amount of water Sarah will drink after the third week of increase, we need to find the 5% increase for each week.

In the first week, the increase is 5% of 224 ounces, which is (5/100) * 224 = 11.2 ounces.
Therefore, after the first week, Sarah will drink 224 + 11.2 = 235.2 ounces (rounded to the nearest ounce).

In the second week, the increase is 5% of 235.2 ounces, which is (5/100) * 235.2 = 11.76 ounces.
Therefore, after the second week, Sarah will drink 235.2 + 11.76 = 246.96 ounces (rounded to the nearest ounce).

In the third week, the increase is 5% of 246.96 ounces, which is (5/100) * 246.96 = 12.348 ounces.
Therefore, after the third week, Sarah will drink 246.96 + 12.348 = 259.308 ounces (rounded to the nearest ounce).

Therefore, Sarah will drink approximately 259 ounces after the third week of increase.
So, the answer is 259 ounces.
