To solve this problem we will use the concepts related to hydrostatic pressure. Which determines the pressure of a body at a given depth of a liquid.
Mathematically this can be described as
[tex]P= \rho gh[/tex]
Here
[tex]\rho[/tex] = Density
g = Gravity
h = Height (Depth)
If we replace the values given in the equation we will have to
[tex]P = 1000 (9.8)(1)[/tex]
[tex]P = 9800 Pa[/tex]
Therefore the pressure at the bottom will be 9.8kPa
