I am considering getting a new aquarium to put in my living room and
it could be as large as 44 x 18 x 18 inches .I know how much the tank
weighs and the water ( 234 litres at a lb a litre) and then there is
the weight of rocks and the cupboard that it sits on .
I was trying to compare it with a bath,filled with water plus a body
in the bath . I can calculate the weight of water and my body weight
is easy enough to get but can anyone suggest what a plastic bath might
weigh .?

A plastic bath weighs not a lot.

A body weighs a little less the its same volume of water. You don't
need the weight of a full bath of water plus body, because as soon as
the body enters the water the water would be displaced (down the drain).

Eureka ! - as they say
