Question

# The body surface area (BSA) of a human being is used to determine doses of medication. The formula for finding BSA is BSA = ,where H is the height in centimeters and M is the mass in kilograms. A doctor calculates a particular dose of medicine for a patient whose BSA is less than 1.9. If the patient is 160 cm tall, what must the mass of the person be for the dose to be appropriate?

Hint:

### Substitute in the equation and solve.

## The correct answer is: 81.225

**Complete step by step solution:**

Here, BSA < 1.9 and H = 160cm

Given that the formula for BSA =

On squaring both the sides, we get

So, the mass of the person must be less than 81.225 for the dose to be appropriate.

Here, BSA < 1.9 and H = 160cm
