Explanation:

Step1: Convert height to inches

1 foot = 12 inches, so 5 feet 10 inches = 5×12 + 10=70 inches.

Step2: Convert weight to kilograms

1 pound = 0.453592 kg, so 220 lb = 220×0.453592 = 99.79024 kg.

Step3: Convert height to meters

1 inch = 0.0254 m, so 70 inches = 70×0.0254 = 1.778 m.

Step4: Calculate BMI

The formula for BMI is $BMI=\frac{weight(kg)}{height(m)^2}$. So $BMI = \frac{99.79024}{1.778^2}=\frac{99.79024}{3.161284}\approx31.56$. Rounding to the nearest tenth, $BMI\approx31.6$.

For a 16 - year - old boy, looking at the BMI chart for boys, a BMI of 31.6 is in the "May be overweight" range.
