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.
This is not from lack of research, but rather from a lack of true consensus. In both hominid species and in humans alone, studies have been performed which plausibly argue that cranial capacity is a significant indicator of intelligence, and other studies successfully argue that it is not.
Furthermore, the vital capacity is used to determine the severity of respiratory muscle involvement in neuromuscular disease, and can guide treatment decisions in Guillain-Barre barrÃ© syndrome and myasthenic. Crisis a normal adult has a vital capacity between 3 and 5. litres normal adult has a vital capacity between 3 and 5 litres. A human's vital capacity depends on age, sex, height, mass, and ethnicity. Lung volumes and lung capacities refer to the volume of air associated with different phases of the respiratory cycle.
