Question

Q.6. A piece of wood measures 4 cm by 2 cm by 9 cm. If it weighs
144 g, then find the density of the wood.​

Answer 1

Answer:

To start, an object’s density  D=m/v , where  m  is its mass and  v  is its volume.

You are given the mass, and calculating the volume of a rectangular object is quite straightforward: v=l/w/h, or in English length times width times height.  

Simply plug in the given values to get your density. Note that your units of density will be g/cm^3, which is commonly used for density, but if your question specified different units you may have to be careful to convert.
