How do you calculate the density of an object or substance?

Density is the measurement of how much mass is contained in a given volume of a substance, and is expressed in units of mass per unit volume. To calculate the density of an object or substance, you need to know its mass and volume.

To get the mass of an object or substance, you can use a balance or scale. Make sure to use the appropriate unit of measurement. For example, in the metric system, mass is measured in grams (g).

To get the volume of the object or substance, you can use various measuring tools depending on the shape of the object.

For regularly shaped objects, such as cubes or spheres, you can use the appropriate formula to find the volume:

• Volume of a cube = length x width x height
• Volume of a sphere = 4/3 x π x radius^3

For irregularly shaped objects, you can use water displacement method. It involves filling a container with water, measuring the initial level of water, placing the object in the water, and measuring the final level of water. The volume of the object is the difference between the final and initial levels of water.

Once you have the mass and volume, simply divide the mass by the volume to get the density.

Density = Mass / Volume

Make sure to express your answer in appropriate units. In the metric system, density is typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
