The density of a substance tells you the mass of that substance per unit of volume.
#color(blue)("density" = "mass"/"unit of volume")#
Simply put, you can look at a substance's density and tell what mass is associated with one unit of volume of that substance.
In your case, the block of wood is said to have a density of
So, a density of
Well, if you get
#126 color(red)(cancel(color(black)("g"))) * ("1 cm"^3)/(0.60 color(red)(cancel(color(black)("g")))) = "75.6 cm"^3#
Rounded to two sig figs, the number of sig figs you have for the density of the wood, the answer will be
#V = color(green)("76 cm"^3)#
