The volume of wood cannot be determined if the density is 0 kg/m³ because volume calculation requires non-zero density. In general, the volume VVV of a substance when given mass mmm and density ρ\rho ρ is calculated as:
V=mρV=\frac{m}{\rho}V=ρm
If the density ρ=0\rho =0ρ=0, this formula becomes undefined for any non-zero mass because division by zero is not possible. Therefore, if the density of wood is 0 kg/m³, the volume for any mass of wood is not calculable or physically meaningful. If the mass is zero kilograms, the volume is obviously zero cubic meters as well. Normally, wood has a density around 700 kg/m³ (typical seasoned wood) for reference.
