Your answer of 2700 g/m

^{3}is correct, but if you present it as 270 g/m3, you are off by a factor of 10, right? 270. is NOT the same as 2700 as it is 1/10th the value. Look at it as follows:2.70 g/cm

^{3}x 1 kg/10^{3}g = 2.70x10^{-3}kg/cm^{3}2.70x10

^{-3}kg/cm^{3}x 1cm^{3}/10^{-6}m^{3}= 2.70x10^{3}kg/m^{3 }(to 3 significant figures)
