Knowing the density of a material enables an engineer or architect to calculate the mass of a building or structure from its volume. This in turn enables them to determine the correct depth of ...

If your students have already learned the meaning of volume and mass, you can easily use those terms to define density as Density = mass/volume ... This is not an easy question and requires a ...

To find the volume of an objects like a cube or a box, measure the length × width × height. If measured in centimeters, the answer will be in cubic centimeters (cm³). Mass is measured in grams. The ...

The same mass takes up a bigger volume - this means the gas is less dense. Density also depends on the material. A piece of iron with the same dimensions as a piece of aluminium will be heavier ...
