Question

the mass of an iron cube having an edge length1.8 c.m is 70g find its density​

Answer 1

given =>

length of cube = 1.8

its weight = 70g

=>volu. of cube = 1.8*1.8*1.8

$5.832cm {}^{3}$

$its \: weight \: = 70 \times 70 \times 70 \\ \\ = > 343000gm \\ \\ = > 343kg = 343000gm \\ \\ = > 343kg \: is \: the \: mass \: of \: iron \\ \: cube$
