Answer 2

Solution:

cross section area of car =A

cross section area of car =Aand length of car l

cross section area of car =Aand length of car lSo, volume of car = (A xl)

cross section area of car =Aand length of car lSo, volume of car = (A xl)And density p = mass/volume

cross section area of car =Aand length of car lSo, volume of car = (A xl)And density p = mass/volumeTherefore mass =p x volume

cross section area of car =Aand length of car lSo, volume of car = (A xl)And density p = mass/volumeTherefore mass =p x volumem=p x Ax|

cross section area of car =Aand length of car lSo, volume of car = (A xl)And density p = mass/volumeTherefore mass =p x volumem=p x Ax|m= pAI.
