The National Academies of Sciences Engineering, and Medicine determined the daily water intake is about 15.5 cups for males per day
How much water should a young man drink per day in liters?
4 cups = 1 qt, 1.06 gts = 1 L

Greetings from Brasil...

According to the annex, we note that

1 qt = 1 quart = 0.95L

To solve this problem, just apply some rules of 3.....

1st - how many qt's are in 15.5 cups

  qt                 cup

   1   ----------     4

   X  ----------   15.5

4 · X = 1 · 15.5

4X = 15.5

X = 15.5 ÷ 4

X = 3.875qt

Last rule of 3 to know how many liters there are in 3.875qt:

  qt                       litres

   1         ----------    0.95

3.875    ----------      Y

1 · Y = 0.95 · 3.875

In a day a young man should drink 3.68L of water
