Pencil Density Exploration

 Given:  density of graphite core material  = 1.46 g/cm³

 Problem: Find the density of the pencil if the core material was removed (i.e. what is the density of the wood excluding the graphite core):

 Instructions:  Show all work beneath the individual question. Record final answers to at least 3 sig figs. 

Final Answer:          ________________________
