Understanding Density: Sand in a Bucket Example Explained Simply

Imagine a bucket filled with sand. It has a certain amount of sand in it, right? We call this amount the volume of sand, which is like how much space the sand takes up in the bucket. In this case, the sand in the bucket takes up 0.12 cubic meters of space, which is like saying it fills that much of the bucket.

Now, let's talk about mass. Mass is how heavy something is. So, the sand in the bucket weighs 18 kilograms. This means that if you were to pick up the bucket with the sand in it, it would weigh 18 kilograms in total.

To find the density of the sand, we need to figure out how tightly packed the sand is in the bucket. Density tells us how much mass (weight) is packed into a certain volume (space). By dividing the mass of the sand by its volume, we can find the density.

So, if we divide the mass of 18 kilograms by the volume of 0.12 cubic meters, we get a density of 150 kilograms per cubic meter. This means that for every cubic meter of sand in the bucket, it weighs 150 kilograms. That's the whole number answer to the question!

In summary, density helps us understand how heavy something is for the amount of space it takes up. In this case, the sand in the bucket has a density of 150 kg/m³, showing us how packed together the sand particles are in that space.
