Video transcript

"hullo students welcome to lido learning's question and answer videos let's have a expect at this question the question says the density of brass is 8.four grams per centimeter cube or gram centimeter minus 3 what practise y'all mean by this statement so this basically is asking nigh what do you hateful past density of of a material so we all know that density let's write downwardly the definition it is equal to mass per unit volume so density of any substance is written equally mass per unit volume this is the bones definition which nosotros accept to utilize here now let'due south look at the question so it is given that brass has a density of viii.4 grams per centimeter cube so since information technology is cm minus 3 we tin can also write it as per centimeter cube and then what do we mean by this so density which is 8.four grams then that'south this means that 8.4 grams volition exist the mass in i centimeter cube and this is the density so information technology shows that viii.4 grams of brass is the mass in ane centimeter cube right or nosotros may say that one centimeter cube book of contumely has mass of 8.4 grams so permit me write that down then this shows that one centimeter cube volume of contumely has a mass of eight.iv grams this is what nosotros mean past this particular argument i hope you take understood this if there is any further doubts please post your comments below thanks"
