What is Johnny's BMI if he is 6'2" and weighs 254 lbs?

To calculate Johnny's Body Mass Index (BMI), the formula used is:

[ \text{BMI} = \frac{\text{weight in pounds} \times 703}{\text{height in inches}^2} ]

In this case, Johnny weighs 254 pounds and is 6 feet 2 inches tall. First, convert his height into inches:

6 feet = 72 inches (since 1 foot = 12 inches, so 6 feet = 6 x 12 = 72 inches)

Adding the 2 inches gives him a total height of 74 inches.

Now, plug in the values into the BMI formula:

[ \text{BMI} = \frac{254 \times 703}{74^2} ]

Calculating:

1. ( 74^2 = 5476 )

2. ( 254 \times 703 = 178762 )

3. Now, divide: ( \frac{178762}{5476} ≈ 32.5 )

When we consider BMI categories, a BMI of 30 or greater typically categorizes individuals as at risk for health issues related to obesity. Since Johnny's calculated BMI falls into the range of 30.
