How do you find the density of a stapler?

Answer 1

So you need to find the volume of the stapler. the mass is easy because you just weigh it. However finding the volume could potentially ruin the stapler. You could calculate the volume of the smaller parts or you could submerge it in a known volume of water and see how much it replaces. Divide Mass by Volume and Disco!

Answer 2

First weigh it, then submerge it in water and measure the displacement in milliliters. Divide weight by volume to get grams/ml.

There is a story about Archimedes, who figured out this method for the first time in his bathtub when he noticed the water level changed when things were put in or taken out. He had been given the job of finding out how pure some gold objects were without destroying them - he suddenly had the answer and ran naked thru the streets of Athens yelling "Eureka!"

Answer 3

water displacement
