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 g

a. 0.015 g/cm3 c. 0.015 g/ml 
b. 10.015 g/ml d. None of the above

anonymous · Answer

$$ \text{Volumetric density} = \rho = \frac{\text{mass}}{\text{volume}} \ \ \propto \ g/cm^3$$
$$V_{rectangle} = L \cdot W \cdot H $$
