Final answer:
The BMI for a man who weighs 154 pounds and is 70 inches tall is calculated to be 22.1. This places him within the normal weight range, as the normal BMI range is from 18-24.9.
Step-by-step explanation:
To calculate the Body Mass Index (BMI) for a man who weighs 154 pounds and is 70 inches tall, we use the formula:
BMI = (Weight in pounds × 703) / (Height in inches ²)
Substituting the values into the formula gives us:
BMI = (154 × 703) / (70 ²) = (108262) / (4900) = 22.1
Therefore, the man's BMI is a) 22.1, which is within the normal weight range. A BMI range from 18-24.9 is considered normal weight. In comparison, a BMI of 25-29.9 indicates overweight, over 30 signals obesity, and a BMI of 40 or more signifies morbid obesity.
An adult with a BMI of 30 or higher is considered obese according to the CDC, and one with a BMI over 40 is classified as morbidly obese. It is important to note that while BMI is a helpful tool in population studies, it may not fully account for individual factors such as muscle mass versus fat content.
