Question

hey guys!! help me..
mass = 252g, volume = 30 cm
find the density: (a) g/cm (b) kg/m
plz show steps
plz tell how to convert g/cm to kg/m

Answer 1

mass =252g
volume =30cm³
density d =
we know that mass = volume x density
density =mass/volume
density d =252/30
d =8.4 g/cm³
In kg/m³
density=( 252/1000)kg /(30/ 100x 100x 100)
density d = 8400kg/m³
Steps to convert g to kg
1kg =1000g
so, 1g = 1/1000kg
252g = 252/1000kg
And
1cm =100m( length)
1cm³=(100 CM)³
30cm³= 30/(100)³.
