Robert is 6' 1" tall and weighs 230 lb. What is his body mass index (BMI) classification?

To determine Robert's BMI classification accurately, it is essential first to calculate his Body Mass Index (BMI) using his height and weight. BMI is calculated using the formula:

[

BMI = \frac{weight , (lbs) \times 703}{height^2 , (inches)^2}

]

In Robert's case, he weighs 230 pounds and is 6 feet 1 inch tall, which converts to 73 inches (since 6 feet = 72 inches and 1 inch adds to that). Plugging in his numbers:

[

BMI = \frac{230 \times 703}{73^2}

= \frac{161690}{5329}

\approx 30.35

]

Once the BMI is calculated, it falls into specific classifications:

• Underweight: BMI less than 18.5

• Normal weight: BMI 18.5 to 24.9

• Overweight: BMI 25 to 29.9

• Obese: BMI 30 and above

Since Robert's calculated BMI of approximately 30.35 falls into the "Obese" category, it confirms the classification is accurate. This classification is important as it helps in
