Average Volume of a Standard Key (for a house)

>>8764896
do a mass to volume conversion via the density of key brass or something

The mass could be easy to find, but I cant seem to find either a density or volume .

>place key in contain of water, measure displacement

Pretty much this. To find the average of all keys, just assume yours is the average and fuck the statistics because who cares it's just a key dude

>>8764942
Google "Archimedes."

>>8764896
just measure the volume of every key in the universe, add them togetherr and divide by the nubmer of keys you measured

>>8764942
google "what alloy are house keys made out of"
google "density of alloy x"

is it really that hard?

Did the old water displacement method with one house key using my kitchen scale.

The uncertainty of the scale is +/- 0.5 g and the mass of the water displaced was measured at 1 g, likely putting it in the range between 0.5 to 1.5 g which would put the volume of the key somewhere between ~0.5-1.5 cm^3

Of course, this is just one key, measured once, on a kitchen scale by a bored engineer.

I am surprised by how few suggested the water displacement method. Brainlets

how the fuck is 5 to 2 'few'?

You could measure several keys for displacement then divide by the number of keys.

what do you need the information for?
