Density is easily calculated if you know the mass of the object and its volume. To find the mass, you simply need to weigh the item on a triple beam balance or a digital scale. Usually, in science, mass  is calculated in grams(metric units). You also need to find the volume of the item. This can be done in one of two ways. If the object is a regular object, such as a rectangle or square shape, simply measure length, width and height of the object in millimeters and multiply these three values to get volume in mm3 or ml. If the object is irregular, you will need a graduated cylinder to find its volume. Simply fill your cylinder with water  to a known level, for example, 25 milliliiters, and then, put your object into the cylinder. The water level will rise because it has been displaced by your object. Subtract the original known amount of water from the new volume in the cylinder. The difference will be the volume of your object. Volume is a measure of how much space an object occupies. Now that you have the mass in grams and the volume in milliliters, you divide Mass by Volume to find the object's Density.
