[C320-list] Weight of a 320

[Graeme Clark]

Nope!
If it floats it displaces the same weight (strictly, MASS)  of water as it’s own mass but less VOLUME of water than its own volume

If it is neutrally buoyant then mass and volume of both are the same

If it sinks then volume of water displaced is same as object but mass of water is less than mass of object

ISTBC!
