Mindless. Distasteful. I still maintain 90% of people are idiots.

Incorrect. The density of the human body is about 90-95% of the density of water. Since the Titanic sunk in cold, sea water let’s assume : human body / water density = 0.9 . Let’s assume Rose weighs 45kg. Since density is calculated as : density = mass / volume. We can easily understand that volume = mass/density. Cold water density is about 1.0 x 10^3 kg/m^3, which means that human density is 0.9 x 10^3kg/m^3. This leads us to the calculation of Rose’s volume : volume = 45kg / 900kg /m^3 = 0.05 m^3. Now let’s take a look at the piece of wood she is using to stay out of the water. It is about 2 meters in length, 0,75 meters in width (average) and 0,1 meters in height. This means that the volume of the wood is : volume = 2 x 0,75 x 0,1 = 0,15m^3. Since wood density (assuming wood is still dry, which is the very best possibility) is about 75% the density of water, we can calculate its weight : weight = 0,15 x 750 = 112, 5 kg. The total weight of Rose and the piece of wood is 45kg + 112,5 kg = 157,5kg. The total volume is 0,05 + 0,15 = 0,2m^3. This means the total density is : density = 157,5 / 0,2 = 787 kg/m^3. Since the total density is about 79% the density of water, 21% of the volume of the system Rose + wood is out of water. Rose’s volume is about 25% of the total volume (0,05 over 0,2). This means Rose is basically out water. Let’s think about Jack now. I will skip all the calculation, but assuming Jack weighs 75kg, the total density of the system is now about 83% of the density of water. This means that less than the 20% of Jack + Rose + wood is now out of the water. Since (by calculating volume as done before) the volume of Jack + Rose is about 43% of the volume of the system, this means that Jack and Rose are now half submerged in the cold water of the north Atlantic Ocean. You lose your body heat about 25 times faster in water than in the air. You can now make your own conclusions. Any discussion ? Hit me up : @yourhomegirlbd
^ SEEE? I knew this couldn’t be true.
When did the meme state that they would survive? It MERELY stated that both could fit on the wood.
