Real-Life Math

As an MLD therapist, you must calculate the volume of a limb. By having this figure, you can compare the swollen limb with the healthy limb. Then you can determine the extent to which the swelling is reducing as a result of your treatments.

To do this, you must first make a mark on the skin every 4 cm from the wrist to the armpit (if using an arm).

Next, measure the circumference of the arm at each space.

To calculate the volume, follow the following steps:

  1. Determine the square of each of the measurements made at 4 cm apart.
  2. Add the squares together.
  3. Divide the total of the squares by pi. This figure is the volume of the limb.

You are trying to determine the volume of a child's arm. Here are the circumference measurements you have:

Wrist: 8 cm
Next: 10 cm
Next: 14 cm
Next: 16 cm
Next: 18 cm
Next: 20 cm
Next: 24 cm

What is the volume of the little boy's arm?
