In simple terms, density is how much stuff is packed into an object. To find density, we need to divide the mass of an object by its volume. For example, imagine a bag of feathers and a bag of marbles; even though they may be the same size, the bag of marbles is heavier because the marbles have more stuff packed into the same space.
Now, let's apply this concept to our marble statue. We know it has a volume of 0.35 cubic meters and a mass of 91 kilograms. To calculate its density, we divide the mass by the volume: 91kg / 0.35m³ = 260kg/m³.
So, the density of the marble statue is 260 kilograms per cubic meter. This means that for every cubic meter of space the statue occupies, it weighs 260 kilograms!
Remember, density helps us understand how heavy or light an object is in relation to its size. The higher the density, the more stuff is packed into the same volume.
Keep practicing and exploring the concept of density with different objects to get a better grasp of this fundamental physics principle!
