matler

what is matler?
Everything that soraun us is made up matler.there air,the animals ,rock plants verything . with cow define matler as all that occupies as spase and can be weigh and flated baloim , we can se that weighed slightly more than un - inflated ballon . when we are studing matler , we use sam basic quantities such as length , surfase , ared , volume, mass, density or temperature . So that we are all using the same units inside we use what is could the international sistem of units .

Dimensions:
Length (l) is the distance betuin two bodies , in (si) units this is measured in metres (m) we also use centrimetres (cm) or kilometres (km) . ew use rules , measuring tapes and so ons when we are measuring length.

Surfase area (s) is the espace ocupied by two dimensions means and with. In (si) units we measuring surfase area is kuare metres (m2) another come units is kuares centrimetres (cm2).

Volume (v): is the space ocupiet by a bodi .if the poten measured in litres eveng in the (si) units is the (m3) the volume or licuis or solides come by measured using measuring sylinder in cas of regular geometry chapes we can use matematical formulas for example: the volume of sphere whit radius are its V5phar=4/3 p,3.
