The pressure on the ground is equal to its own weight. That is, 2.4x10.4kg times the acceleration of gravity (generally, the power is expressed by symbols).
Pressure is equal to pressure divided by area;
When sailing on water, buoyancy is equal to its own gravity, and the volume of boiling water multiplied by the density of water is equal to the mass of the water tank.
Do the math yourself. It's simple.
