Each of those lines represents 1 centimetre, with the number tell you how man centimetres between that line and the first line (either unlabelled, or labelled 0).
Between those line there may be 10 little lines with the fifth one longer than the rest, but shorter than the labelled lines. These are millimetres, which are also 0.1 cm each.
The shorter lines represent one millimeter (mm). The longer lines with numbers next to them represent one centimeter (cm) (10 millmeters) High precision calculation for life or science: keisan dot casio dot com
you draw straight lines with a ruler

The easy way to find the length of a pencil is to use a ruler to measure it. A "small" ruler might not make it, but a "regular" one foot ruler will do the job nicely.
using a ruler, draw any two lines that cross each other

A length of two units!
On a typical inch ruler the smallest lines are 1/16th dimensions. The next biggest are 1/8th", then 1/4", and finally 1/2".
It measures length, and it also helps you draw straight lines
something like texture, color, smell, sound and taste
The question is somewhat vague, but I think you may be asking: Why are different lines of latitude marked with different numbers ? I'd compare that to the question: Why are different marks on the ruler marked with different numbers ? The reason is because both of them are systems invented to help you measure things. The marks on the ruler help you estimate the length of things that you place the ruler on, by showing you where a few exact lengths are. And the horizontal lines on a map or globe help you estimate the latitude of places on the Earth, by showing you where a few exact latitudes are.
there should be the cm lines- the long ones with the numbers underneath. Inbetween these should be a series of shorter lines indicating the millimetres.
The average length of a ruler is 12 inches.
Measuring implies using a measuring device of some kind. If you mean to construct a hexagon without a protractor or ruler, that's different. Constructions in geometry require only a compass and a straightedge (a ruler, but you ignore the numbers). A hexagon can be made of 6 equilateral triangles; choose any length for the side and construct them connected together, using only the compass to set the length and the straightedge to draw straight lines between points.
why are the division lines on a ruler diffrent lengths
There are 10 milimeters in 1 centimetre. The numbers on a ruler are usually centimeters. The little un-numbered lines that divide up the centimeters mark the milimeters.
the tool of length is a RULER!
