If the volume of a cube of wood is15.625 cm3 and its mass is 10.00 grams, show the calculation for the density of the wood

To find density, use p=m/V, which means density equals mass divided by volume.

If the volume is 15.625 cm^3 and the mass is 10 grams, just divide 10 by 15.625.

10/15.625 = 0.64

So the density is 0.64 mass per unit volume.
