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.
Measuring of manâs potential intellectual capacity from sources other than direct observations and testing is derived from direct, indirect and inferential data. The direct data is obtained from measuring cranial capacity and examining casts which âexposeâ the interior of the skull. The indirect evidence comes from the study of comparative brain sizes, which is based on the assumption that there is a correlation between brain size and configuration, and behavioural studies.
