what does density mean
http://dictionary.reference.com/
I think it the amount of volume in an object
Nope. That's not what the dictionary shows.
Density refers to the amount of mass in a given volume of a substance. It measures how compact or concentrated a material is. To calculate density, you can use the formula:
Density = Mass / Volume
To find the mass of an object, you can use a balance or scale to measure it. Typically, mass is given in grams (g) or kilograms (kg).
To determine the volume of an object, it depends on the shape of the object. For regular-shaped objects such as cubes or rectangular prisms, you can measure the length (l), width (w), and height (h) and then calculate the volume using the formula:
Volume = l × w × h
For irregular-shaped objects, you can use techniques such as displacement or measuring the dimensions and using specific formulas for their shapes.
Once you have both the mass and volume, you can divide the mass by the volume to find the density of the material.
Keep in mind that density is typically reported in units such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). It is important to note that the density of a substance remains constant regardless of the size or amount of the material.
