Answer 2

Note:

(1) 1 cm^3 = 0.000001m^3.

(2) 1 kg = 1000 grams.

(3) 1 litre = 1000cm^3.



Now,

Given Volume of Kerosene = 4.40kg.

                                              = 4400g.

Given Mass of kerosene = 5 litres

                                          = 5000cm^3.



(a) CGS System:

= 4400/5000

= 0.88 g/cm^3




(b) SI System:

= 4.40kg/5000cm^3

= 4.40kg/0.005m^3

= 880kg/m^3.



Hope this helps!
