Calculate the Body Mass Index (BMI) for a 6 foot tall man weighing 200 pounds
The Correct Answer and Explanation is:
To calculate the Body Mass Index (BMI), we use the formula:
[
BMI = \frac{{\text{{weight in pounds}}}}{{\text{{height in inches}}^2}} \times 703
]
Step 1: Convert height to inches
The individual is 6 feet tall. Since there are 12 inches in a foot:
[
6 \, \text{{feet}} \times 12 = 72 \, \text{{inches}}
]
Step 2: Square the height in inches
Now, we square the height in inches:
[
72^2 = 5184 \, \text{{inches}}^2
]
Step 3: Apply the BMI formula
Now that we have the weight (200 pounds) and the height squared (5184), we can plug these values into the BMI formula:
[
BMI = \frac{{200}}{{5184}} \times 703
]
[
BMI = \frac{{200 \times 703}}{{5184}} = \frac{{140600}}{{5184}} \approx 27.1
]
Conclusion:
The BMI of the individual is approximately 27.1.
Explanation:
BMI is a measure that helps assess whether an individual has a healthy body weight relative to their height. It is widely used as an indicator of body fat and potential health risks associated with being overweight or underweight. A BMI between 18.5 and 24.9 is considered normal, while a BMI between 25 and 29.9 falls into the overweight category, and 30 or above is classified as obese.
In this case, the calculated BMI of 27.1 places the individual in the “overweight” category. While BMI is a helpful screening tool, it is not perfect as it does not account for muscle mass, bone structure, or fat distribution. For example, a muscular person might have a higher BMI but not have excess body fat. It’s important for individuals to consider other factors, such as waist circumference, body composition, and overall health when evaluating their weight. Additionally, consulting with a healthcare provider is crucial for understanding any health implications of BMI in relation to a person’s unique body composition.
