-in [geometric measurements], length is the ‘most extended dimension’ of an [object]-
.
-in the “international system of quantities”, ‘length’ is any ‘quantity’ with ‘dimension distance’-
.
(in other contexts, ‘length’ is the measured dimension of an ‘object’)
(for example, it is possible to cut a length of a ‘wire’ which is shorter than ‘wire thickness’)
.
(‘length’ may be distinguished from ‘height’…)
(which is ‘vertical extent’)
(…and ‘width (or ‘breadth’)…)
(which are the distance from side to side / measuring across the object at ‘right angles’ to the ‘length’)
.
–length‘ is a measure of [1 dimension]-
.
(whereas area is a measure of ]2 dimensions])
“length squared“
.
(and volume is a measure of [3 dimensions])
“length cubed“
.
(in most ‘systems of measurement, the unit of ‘length’ is a ‘base unit’ from which other ‘units’ are defined)
