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.
Measure: To estimate the cranial capacity of each skull in the Gizmo, measure the area of the part of the cranium that houses the brain. This part of the cranium is roughly behind the red line in the diagram at right.
