According to the formula in the material, a person weighing 192 pounds would need how many 8 oz glasses of water per day?

• A. Eight
• B. Twelve
• C. Sixteen
• D. Ten

Answer: (B)

Applying a weight-based water intake rule: you estimate daily water need by taking about half your body weight in ounces. For someone weighing one hundred ninety-two pounds, half of that is ninety-six ounces per day. Since each glass is eight ounces, ninety-six ounces equals twelve glasses. So the required amount is twelve eight-ounce glasses per day. For reference, eight glasses would be sixty-four ounces, ten glasses would be eighty ounces, and sixteen glasses would be one hundred twenty-eight ounces—only the twelve-glass amount meets the ninety-six-ounce target.
