the titanic had mostly teak, maple and oak furnishings no reason to believe they used less nice doors.
the proportion of the door height to length is about 8:3 at best nowhere near the 6:3 you suggested
and a ten cm thick door is almost four inches thick a bit thick even for the titanic.
so using a door volume of 2.235m*.8381m*.1m(using this because i have no way to gauge thickness)(other measurements obtained through height of Kate Winslet (5’6”)
first buoyant force = 2.235m*.8381m*.1m*1010kg/m^3*9.8j/kg = 1850j
that means a completely submerged door gives 1850j of upward force total
now the door is more likely to be around 700kg/m^3 simply because that’s pretty normal for teak maple and oak but will make it fun and say the door is 600 kg/m^3
so now force exerted by gravity on the door 2.235m*.8381m*.1m*600kg/m^3*9.8j/kg = 1100j
this gives us 750j to support two people is not happening 76.5 kg is the max that door is holding
your objection is invalid, and assumes a 6’2” 121 pound Kate Winslet, dry wood(it’s in the water so that’s unlikely), 4 inch thick doors made of pine, and on top of that they are wearing wet clothes which gives them even more weight.
Your assumptions are bad and you should feel bad!
