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.
Cranial capacity â the interior volume of the cranium, where the brain is housed. Humans have a cranial capacity of 1,000â2,000 cm3. Chimpanzees have a cranial capacity of 300â400 cm3. Cranium â the portion of the skull that does not include the mandible (lower jaw).
