What the solution ? The relative density of type of wood is 0.8 find the density of the wood in kg/m3 ?

The relative density, also known as specific gravity, is defined as the ratio of the density of a substance to the density of a reference substance. In this case, the reference substance is typically water. Given that the relative density of the wood is 0.8, we can use the fact that the density of water is approximately 1000 kg/m³ to find the density of the wood in kg/m³. Density of wood = Relative density * Density of water Density of wood = 0.8 * 1000 kg/m³ Density of wood = 800 kg/m³ Therefore, the density of the wood is 800 kg/m³.
