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.
What is 'normal' intracranial pressure? Intracranial pressure, the pressure of the cerebrospinal fluid that surrounds the brain and spinal cord is measured in mm/H2O or cm/H2O. Normal intracranial pressure is considered to be 8 - 20cm (or 80 - 200mm). Recently studies determined that an LP opening pressure of over 25cm (250mm) is classified as intracranial hypertension in both adults and children.
