A container has a large cylindrical lower part with a long thin cylindrical neck. The lower part of the container holds 12.5 m^3 of water and the surface area of the bottom of the container is 5.00 m^(2 ). The height of the lower part of the container is 2.50m and the neck contains a column of water 8.50m high. The total volume of the column of water in the neck is 0.200 m^3. What is the magnitude of the force exerted by the water on the bottom of the container? why is the volume given i dont think this information is needed to solve the problem cant we just use P = Po + (density)gh and we know the total height
