Answer 2

Studies on human brain size, largely based on participants of European ancestry, tend to find an average adult brain volume of 1260 cubic centimeters (cm3) for men and 1130 cm3 for women. There is, however, substantial variation between individuals;[1] one study of 46 adults, aged 22–49 years and of mainly European descent, found an average brain volume of 1273.6 cm3 for men, with a range of 1052.9 to 1498.5 cm3, and 1131.1 cm3 for women, with a range of 974.9 to 1398.1 cm3.[2]

The right cerebral hemisphere is typically larger than the left, whereas the cerebellar hemispheres are typically closer in size. The adult human brain weighs on average about 1.28 kg (2.8 lb).[3]
