A block of wood measuring 10 in x 8 in x 2 in, weighs 3 lbs 10 oz. What is the density of wood in kg/m^3.
***
density=weight/volume
..
10 oz=10/16 lb=0.625 lb
weight=3 lbs 10 oz=3.625 lbs
volume=10*8*2=160 in^3
density=3.625/160=0.022656 lbs/in^3
1 lb/in^3 = 27679.9 kg/m^3
density=.022656*27679.9≈627 kg/m^3
