A rectangular block has dimensions 1.5cm x 3.2cm x 3.9cm and a mass of 61g.
Determine the density in SI units
My taking on the question,
Mass= 0.061kg
Volume= 0.1872m
Density=0.061kg/0.1872m=0.3258547kgm^3
Can someone please tell me where I'm going wrong?

V = 0.015*0.032*0.039=1.872*10^6 m^3.
Mass = 0.061 kg.
D = 6.1*10^2kg/1.872*10^6m^3
D = 3.26*10^4 = 32,600 kg/m^3. 
61g/18.72m
equals 61000g/1872cm
32.585g/cm
changed to 3258.54 kg/m
