Length is commonly understood to mean the most extended dimension of a fixed object. [ 1] However, this is not always the case and may depend on the position the object is in. Various terms for the length of a fixed object are used, and these include height, which is vertical length or vertical extent, width, breadth, and depth.
Mean length from cervix to introitus: 6.3 cm (2.5 in). Mean width: at the proximal vagina: 3.3 cm (1.3 in); at the pelvic diaphragm: 2.7 cm (1.1 in); at the introitus: 2.6 cm (1.0 in) A 2006 U.S. study of vagina sizes using Magnetic Resonance Imaging (MRI) on 28 volunteers between 18 and 39 years old, with heights ranging from 1.5 to 1.7 metres ...
2,500,000 L (2,500 m 3; 88,000 cu ft), assuming a nominal depth of 2 m. About 2 acre-feet . There must be two spaces 2.5 m (8 ft 2 in) wide outside lanes 1 and 8 (in effect, two empty lanes). [ 3] The length of 50 metres (164 ft) must be between the touch pads at the end of each lane, if they are used. [ 3]
Four-dimensional space ( 4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.
The Amazon River has an average discharge of about 215,000–230,000 m 3 /s (7,600,000–8,100,000 cu ft/s)—approximately 6,591–7,570 km 3 (1,581–1,816 cu mi) per year, greater than the next seven largest independent rivers combined. Two of the top ten rivers by discharge are tributaries of the Amazon river.
For its first century, the width and length of ships that may transit the canal was limited by the Pedro Miguel Locks; their draft by the canal's minimum 12.6 m (41.2 ft) depth; and their height by the main span of the Bridge of the Americas at Balboa.
On average, the depth of the Bay is 21 feet (6.4 m), including tributaries; [15] over 24 percent of the Bay is less than 6 ft (2 m) deep. [16] Because the Bay is an estuary, it has fresh water, salt water and brackish water. Brackish water has three salinity zones: oligohaline, mesohaline, and polyhaline.
A ruler, depicting two customary units of length, the centimeter and the inch. A unit of length refers to any arbitrarily chosen and accepted reference standard for measurement of length. The most common units in modern use are the metric units, used in every country globally. In the United States the U.S. customary units are also in use.
