How do you find the density of an object?


Quick Answer

To find the density of an object, calculate its volume and mass, and divide the mass by the volume. Use the appropriate formula for volume calculation of the object you are working on. To measure an object's mass, use a balance.

  1. Calculate the volume of the object

    In order to calculate the volume of the object, first measure the necessary dimensions of the object that are required for its volume calculation. For instance, if the object is cubical shaped, measure the three sides of the cube. If the object is spherical, measure its diameter. Use appropriate tools to take these readings, and note them down along with their unit. Take all readings in the same unit, and then use these values in appropriate equations to calculate the volume of the object.

  2. Measure the mass

    Carefully weigh the object using a balance, and note its mass along with the appropriate unit.

  3. Calculate the density

    After carrying out the necessary operations and finding the volume and mass of the object, divide the mass by the volume. Use the units that were noted down earlier. After the final calculation, the unit of density is written in a mass-per-cubic-length format, such as kilograms per cubic meter or pound per cubic feet.
