Question

what is density ?How can we know the density of an object?

Answer 1

The number of things or people in a place I relation to its area is called density.

Divide the objects by its volume.using a calculator, or by hand, if you are feeling adventurous, simply divide the mass quantity in grams by the volume value in cubic centimetres. For a 20 gram mass that takes up a volume of 5 cubic centimetres, the density is 4 grams per cubic metre.
