Quantitative observation.
The coccyx IS the tailbone, and its length varies depending on the person.
The anal canal is approximately 2.5-4 cm (1-1.5 inches) long in adults. It extends from the anus to the rectum and is responsible for the elimination of waste material from the body.
The surface area of a cube with side length ( s ) is ( 6s^2 ) and the volume is ( s^3 ). For a cube with side length 2 cm, the surface area is ( 6(2^2) = 24 ) cm(^2) and the volume is ( 2^3 = 8 ) cm(^3). The ratio of surface area to volume for this cube is ( \frac{24}{8} = 3 ).
The lifespan of a worm can vary depending on the species, but on average, most worms live for about one to eight years. Some species, like earthworms, can live up to 6-8 years in optimal conditions.
In adults, the trachea or windpipe 1inch (2.5centimeters) in diameter.
Because it's a numerical observation
A rectangular prism that is 6 cm long, 2 cm wide and 5 cm high has a volume of 60cm3
L = ( 2 in ) ( 2.54 cm/in ) = 5.08 cm
A small measures 15 cm .It is 15 cm long . It means 2 small ruler will be equal to 30 cm and 5 cm of 3rd ruler . It is 35 cm long .
6 + 6 + 2 + 2 = 16 cm
10*2+5*2 = 30 CM
A square with a side length of 2 cm has an area of 4 square cm.
it depends what type of earthworm it is. The typical North American or European worm is 20cm. However the giant Gippsland earthworm, Megascolides australis, of Australia averages 100 cm long and 2 cm in diameter and can reach 3 m in length.
Two feet = 60.96 cm
66 cm is 2 feet 2 inches.
