What is the BMI of someone who weighs 156 pounds and is 5'7" tall?

Answer :

To calculate the Body Mass Index (BMI) of someone who weighs 156 pounds and is 5 feet 7 inches tall, we use the following formula for BMI:

[tex]BMI = \frac{weight ext{ (lbs)}}{height^2 ext{ (inches)}} \times 703[/tex]

Here's how to calculate it step-by-step:

  1. Convert height into inches only:

    • 5 feet 7 inches is equivalent to 67 inches because there are 12 inches in a foot.
  2. Insert the values into the BMI formula:

    • Weight = 156 pounds
    • Height = 67 inches

    The formula becomes:

    [tex]BMI = \frac{156}{67^2} \times 703[/tex]

  3. Calculate the height squared:

    • [tex]67^2 = 4489[/tex]
  4. Divide the weight by the height squared:

    • [tex]\frac{156}{4489} \approx 0.03476[/tex]
  5. Multiply the result by 703 to get the BMI:

    • [tex]0.03476 \times 703 \approx 24.43[/tex]

The BMI of this person is approximately 24.43. A BMI between 18.5 and 24.9 is considered to be a normal or healthy weight range for adults according to most health authorities.
