Ya all missing the point :rolleyes:

If he goes for the sitting in the bath himself then he's gotta sit there till the sealant goes off :LOL: :LOL: :LOL:

Id go with the filling it up with water ;)

even better, get the wife to sit in it while sealent dries, and bu##er off down the pump, helps if she's a big fatty.

Well, if a bath-full of water weighs 150 kilos, and a 100 kilo body climbs into it, the total weight will be 350 kilos, no matter how much the water is displaced....

Absolute rubbish

if the bath is filled to the overflow, and you get in, you will displace water which will go down the overflow or slop over the side.

Try it.

Then stand in the bath. Still applying your full weight and displace hardly any water.

I'm no mathematician either but............

true when the argument revolves around the parameter of the bath being full.

however, the density of a human body is greater than that of water.
therefore the volume of water displaced will have a specific weight.
that will be less than the object, (in this case a human body) that has displaced said volume of water.
displacement is a measure of volume, density is calculated dividing the mass by the volume.

p =m/v in si units

No, it won't because if the bath is full when ones climbs into it, a volume of water equivalent to the volume of the body entering the bath will climb out.

I believe it is called Archimedes Principle.

As we're all adding conditions, I'll add that bath-full in this context means the normal level of bath fill, say half-way up the sides, as the OP intended, and all the water remains contained in the bath,........

Right. To compensate in some small way for the weight of the human body, our bath filler floats a washbowl in the bath with a few blue bricks in it, whilst he buzzes off to the pub. The bowl leaks, and sinks. Does the level of the water rise or fall, or remain the same? (Conditions: there is no overflow, the plug is watertight, there is no water gain or loss, and the water level is well below the height of the sides.)

And if you really want to waste a few brain cells, our favourite mad scientist puts a half-filled glass of water on the scales. He then dips his finger in it without touching any part of the glass (Don't ask why). Do the scales read more, less or the same?
