If the perimeter of the hexagon is 72, then each side of the hexagon is 72/6 = 12. Therefore, one side of the square is also 12, since the hexagon and the square share a side, â¦ so the area of the square is 12 x 12 = 144 cm.
Making the world better, one answer at a time. I think the cranial capacity is a good indicator of the body because it helps use to think about what we do.
Normal tidal volume is 6-8 cc/kg. Normal vital capacity is 60 cc/kg +/- 20% (i.e. 10-fold increase of TV), and is correlated with the ability to cough and take deep breaths. Inspiratory capacity (IC, the maximal volume inspired from FRC) is one of the only tests that can detect extrathoracic airway obstruction.
