To have knowledge about their property in the real physical world. You can also calculate how much mass an object has if you know how big it is.

For example:

* Low density objects floats on water.

* High density objects sink in water.

What two things do you need to know to find the density of an object?

To find the density of an object, you need to know its mass and volume. Density is calculated by dividing the mass of the object by its volume.


What two things do you need to know to work out the density of an object?

To work out the density of an object, you need to know its mass (weight) and volume. Density is calculated by dividing the mass of the object by its volume.


What things must you know to find the density of a material?

To find the density of a material all you need to know is the mass and volume of the substance. if you knw the mas and volume...finding out the density is very simple...all you need to do is mass/volume and you will have the density of that substance!


What are you things do you need to know about a substance to determine its density?

it's mass, and it's volume.


What two thing you need to know to calculate density?

Density is mass per volume, so you need to know mass and volume.


Can density be measured on its own without mass and volume being calculated or given?

No, because density is the ratio of the mass and volume and you need to know them - explicitly or implicitly.No, because density is the ratio of the mass and volume and you need to know them - explicitly or implicitly.No, because density is the ratio of the mass and volume and you need to know them - explicitly or implicitly.No, because density is the ratio of the mass and volume and you need to know them - explicitly or implicitly.


What two quantities do you need to know in order to calulate density?

To calculate density, you need to know the mass of the object and its volume. Density is calculated by dividing the mass of the object by its volume.


Why is density important when determining what the object is made from?

Because if u know the denstiy you know what the components of the material is. By knowing that you would know the mass and volume.


What information do you need to know about an object to find its density?

To find the density of an object, you need to know its mass (in grams) and volume (in cubic centimeters or milliliters). Density is calculated by dividing the mass of the object by its volume.


What are two things you need to know to calculate density?

Mass and volume. You divide the mass by the volume to get density with the corresponding units. Mass and volume. Density = mass/volume Often, mass is in grams and volumes in milliliters. Water has a density of 1g/ml. Air has a density of about 0.0013g/ml. Lead has a density of 11.34g/ml.


What two pieces of information do you need to measure an objects' density?

you need to know its mass (weight) and volume; density is mass/volume


What the density of a mango if its mass is 30g?

Density depends on 2 things, mass and volume. If you don't know the volume you cannot calculate the density.
