Answer
We can rank the floors according to the force on them due to the water:
$e \gt b =d \gt a = c$
Work Step by Step
As we move deeper under the water surface, the pressure increases.
Since each floor has the same area, the force will be greater when the surface is located deeper under the top surface of the water.
We can rank the floors according to the force on them due to the water:
$e \gt b =d \gt a = c$
