Question

Calculate the density of a rectangular piece of wood from the following data:length: 25 cm. width: 10 cm. height: 4 cm. mass: 15 ga.0.015 g/cm3c.0.015 g/mlb.10.015 g/mld.none of the above

Answer 1

Remember that D=m/v 

to find the volume remember the equation v=LWH 
V=25*10*4=1000cm^3 
M=15g 

Dm/v=15g/1000cm^3=0.015g/cm^3
