Weight of 6.41×1010 number of cells is 1.45 Kg i.e, 1.45×[tex]10^{3}[/tex] gm. So, Weight of 1 (one) number of cells is= [tex]\frac{1.45X10^{3} }{6.41X1010}[/tex] gm = 0.2239 gm.
Assuming that each cell was completely filled with water, from density, Volume of 1 gm water is 1 ml, so volume of 0.2239 gm water is 0.2239 ml. That means, volume of each cell is 0.2239 ml= 0.2239×[tex]10^{-6}[/tex] m³. If each cell is considered as cube, volume of cube=(length of each side of cube)³= 0.2239×[tex]10^{-6}[/tex] m³.
So, length of each side of cube= ∛(0.2239×[tex]10^{-6}[/tex]= 6.07×[tex]10^{-3}[/tex] meter.
