How do you measure the density of an empty school bag?

Answer 1

To measure the density of the empty school bag including the air in the bag, you

should be able to simply weigh it, and measure its dimensions, and calculate the

density, which is weight divided by volume. Bags have a more or less rectangular

shape, so the volume is simply length times width times height. If you want to

measure the density of the material from which the bad is made, that is a little more

complicated, and might require you to squeeze the bag into some kind of compact,

easily measured shape, that does not contain air.

Answer 2

To measure the density of an empty school bag, you would divide the mass of the empty bag by its volume. First, weigh the bag to find its mass. Then, measure the bag's volume by filling it with a known quantity of water and measuring the displacement. Divide the mass by the volume to determine the density.
