Question

The density of wood is 0.65 $gc{m}^3$ in CGS system. Its density in SI system is

• A. 65 $kg{m}^3$
• B. 6.5 $kg{m}^3$
• C. 650 $kg{m}^3$
• D. 0.65 $kg{m}^3$

Answer 1

The correct option is C 650 $kg{m}^3$

As 1 gm per cc = 1000 kg per mc

so 0.65 gm per cc = 0.65 (1000) kg per mc = 650kg per mc ( where cc = centimetre cube) and mc = metre cube)

hence option (C) is correct
