Final answer:
To calculate the BSA of a man, you can use the Dubois formula which takes into account the man's height and weight. In this case, the man is 5 feet 6 inches and weighs 168 Ib. By plugging in these values into the formula, you can calculate his BSA.
Step-by-step explanation:
The BSA (Body Surface Area) of a man can be calculated using the Dubois formula:

In this case, the man's height is 5 feet 6 inches, which is equivalent to 66 inches. His weight is 168 Ib. We can convert this weight to kilograms by dividing it by 2.205 (1 Ib = 0.453592 kg).
Plugging in the values into the formula:

Solving this equation gives us the BSA of the man.
