Volume of a Human Brain The volume of a human brain, otherwise known as cranial capacity, varies depending on several factors, such as age, environment, and body size. The volume is usually measured in cubic centimeters (cm 3 or cc).Modern humans have cranial capacities from 950 cm 3 to 1800 cm 3, but the average volume of a modern human brain is 1300 cm 3 to 1500 cm 3.Viktoriya Shchupak -- 2001.heir brains were about the size of those of present-day gorillas, about 350 to 450 cubic centimeters in volume, as compared with an average volume of about 1450 cubic centimeters in modern humans..

- The relationship between brain size and intelligence doesn’t have to do with actual brain weight. It has to do with the RATIO of brain weight to the entire body weight. For example, human beings have a ration of about 1-to-50. Most other mammals have a ratio of 1-to-180. For birds, the ratio is 1-to-220.

- The average human brain weighs about 1360 grams, or 3 lbs. That’s about four times lighter than an elephant brain. The heaviest mammalian brain is found in the sperm whale – weighing 7711 grams (17 lbs). Larger brains are needed, in part, to control larger muscles. At the other end of the scale is the owl brain that weighs just over two grams. A bullfrog's brain is about one-tenth smaller than that.

- The average adult human brain weighs about 3 pounds – the same weight as the average brain of a dolphin (which is also a very intelligent animal). But there are animals with larger brains that are not considered to be as intelligent as a dolphin. For instance, a sperm whale has a brain that weighs about 17 pounds. On the other hand, some relatively “smart” animals have small brains – for example, dogs and orangutans: A beagle's brain is about 2.5 ounces, and an orangutan's brain is about 13 ounces.

- An adult human's brain weighs between 1300 and 1400 grams (about 3 pounds). A sheep's brain weighs about 140 grams.     Given that the density of both brains is about t … he same, we can safely say that the cerebral hemisphere is much larger in humans. think the sheep cerebrum has less Yes, the sheep cerebrum does have less of the convolutions and sulci, because the human cerebrum has evolved mental capacity over time. 1 person found this useful.
