The approximate number of cells in the human body is 3.72 x 10^13.
Approximately, it is one half.
The [human] population density.
The human brain is used 100%. Some parts may show more activity than others and some parts may be used more often than others. But every part of it is in use. Studies of brain damage have shown that there is almost no part of the human brain that can be damaged without loss of abilities. The 10% use of the brain is an urban myth. The quote has been false attributed to many people, among those is Albert Einstein.

Well... you can make fists with your hands and put your fists together... that is the approximate size of your brain...
Its mass and volume!
There are several ways to measure the human brain: weight (about 3 pounds), volume, intelligence.
The human body has a density close to that of water ~ 1000 kg/m^3 an average person weight maybe 70 kg, which gives an approximate body volume of V=m/M = 70/1000 = 0,07 m^3 Although, a human body density could definitely change depending on anything that could be implanted into the body, and since fat can float (think of soap) it should alter the values accordingly.
The volume of the average adult human brain is around 1400 cm3. This is also therefore probably a reasonable estimate for the internal volume of the human skull.Granite has a density of approximately 2.75 g/cm3.2.75 x 1400 = 3850 g.As such approximately 3.85 kg of granite could fit in a human skull.
The mass of an adult human brain is about 1.3 to 1.4 kg.
Because humans breathe, which means our volume changes significantly with each breath (by a few litres) but our mass stays the same. Since density is mass/volume, the density changes with every breath too.
Approximate human brain length 15cm, approximate brain weight 1400 grams. Have a great day!
The sun has a volume of 1.412×1018 km3. Assuming a base of an 82 kg (~180 lb) human, and an approximate human density of 1062 kg/m3, we reach an average human volume of about 77.2 cm3. This gives us an approximation of 1.829x1021 (1.8 sextillion) people that could fit in the sun. The current population of Earth is estimated to be around 7.033 Billion. Which is to say, you would have to multiply Earth's population by 260 Billion in order to get close to filling the volume of the sun.
i think the approximate speed of a human is 7.50 yards a second
