Final answer:
The formula for BSA is not provided, but the formula given is for calculating BMI, which is [weight (lb) × 703] ÷ height(in)². BMI is used to categorize individuals as underweight, normal weight, overweight, or obese. BMI has limitations because it doesn't account for muscle mass, bone density, and individual body composition differences.
Step-by-step explanation:
Calculating Body Surface Area (BSA)
The correct formula for calculating BSA from pounds (weight) and inches (height) is not provided in the options listed. However, the formula given in the question refers to calculating the Body Mass Index (BMI), not BSA. BMI is an estimate of body fat based on weight and height. To calculate your BMI, multiply your weight in pounds by 703 and then divide the product by your height in inches, squared. The BMI formula is expressed as follows:
BMI = [weight (lb) × 703] ÷ height(in)²
BMI is a useful measure to determine if a person is underweight, normal weight, overweight, or obese. According to the BMI scale, a BMI below 18 is generally considered underweight, over 25 is overweight, and over 30 is classified as obese. The subject of BSA is different and for its calculation, a different set of formulas is used, some of which incorporate both weight and height measurements.
Limitations of BMI
While BMI is a quick and non-invasive way to screen for potential health issues, it does have limitations. It does not take into account muscle mass, bone density, overall body composition, and racial and sex differences. For these reasons, it may not accurately reflect a person's body fatness or health status.
