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.
A cranial capacity of 1,000 cc, for example, includes brain tissue plus non-brain material such as roots, trunks of twenty-four cranial nerves, the thick dura mater, two thinner inner coverings called the arachnoid and pia mater, and cisterns which are areas containing fluid, many blood vessels with venous sinuses, blood and cerebrospinal fluid.
