We use Density when we use to describe how much space an object takes up in relation to the amount of matter in that object. In other words, density is the amount of mass per unit of volume. If an object is heavy and compact it has a high density. So, if we know the volume and mass of an object, we can calculate the density using the formula p=m/v where the "p" is Latin letter for density, then "m" for mass and the "v" is for volume. There is a clear relationship between mass, density and volume. Unlike mass and volume, if you increase or decrease the amount of material, it does not increase or decrease the density.
Gathered two objects to find the density of: cereal box and hair gel.
Mass values were provided directly by the manufacturer information.
Measured the dimensions of each object using a ruler.
Recorded my dimensions in my notebook.
Found a reference table to do mass and length conversions
Computed all my calculations.

Using a ruler, we measured the dimensions of the two objects (cereal box & hair gel). After measuring the dimensions in centimeters, we converted the dimensions from centimeters to meters and put it in the data table.
For the mass, there was no need to approximate or weigh the objects. The values were provided in the manufacturer information.
Some potential sources of error:
Possible defections of the product (may affect the mass in some way if, for example, the product was taller or wider than usual)
Objects used may not be suitable for experiment (an irregular surface, containers, etc.) in comparison to objects like wood blocks or other simple objects
All in all, we were able to successfully determine the density of the cereal box and the hair gel. There were no difficulties regarding the measuring of the objects’ dimensions, and we believe we were able to calculate the volumes of the two objects (one object was a cube, the other was a cylinder, thus , and ). Using the calculated volume values and the mass values, we used the density formula () and calculated the density values of the cereal box and the hair gel.
