Answer 1

VAV po 1000 Given - Mass of non model (m,n) - 5.82kg Density of Iron (Leo) 2 1000kg/m3 wekhow that, Mass = volumex Density =) Meº=Voxfo 5:02 3 Veox 1000 Ves volume of veo= 5.02 0.005 82 m3 iron mood! Now same die is used for gold model so its volume will be same Ive = Veo = 0.00502 m3 vg volume for gold model. We know density of gold (Ag) = 19.3x103 1g/m3 mass of gold (mg) -0.00502X 19.3x103 mg = = 112.326 kg. And- Vg x fg
