The density of an object is the object’s mass divided by its volume. The density is characteristic of the material that the object is made of, and its value can help to identify the material. Except ...

We've learned that the volume of a cuboid is its length multiplied by its width multiplied by its height (\(l \times w \times h\)). The area of the green shaded end of the cuboid (the cross section) ...

It is tempting to think that some materials are always heavier than other materials. For example, someone might say that metal is heavier than air. But it depends on how much of each material there is ...

In my previous post about a floating Saturn, I hinted that I could write about the methods we can use to find the density of Saturn. Oh, and once again, the density of Saturn is lower than the density ...
