The pressure does not depend upon the waterbed area.
Calculate (water density)*g*(thickness)
1000*9.8*0.30 = _____. N/m^2
Find the pressure exerted by a waterbed with dimensions of 2m x 2m which is 30 cm thick. (hint:use density of water)

2940Pa
P=F/A
PRESSURE OF LIQUID = pGH
ALWAYS GRAVITY IS =10
p IN THE PRESSURE OF LIQUID FORMULAE IS RHO OR DENSITY
HEIGHT= 30 CM IN M IS 0.3
SO WHEN WE HAVE ARE DENSITY , GRAVITY, HEIGHT WE ALSO HAVE A LENGHT AND WIDTH WHICH ARE 2M*2M SO WE HAVE DERIVED A FORMULAE WHICH IS
PRESSURE = PGH*A
SO = (1000*10*0.3)*2*2
SO = (1000*10*0.3)*4
SO = (10000*0.3)*4
SO = 300*4
YOUR ANSWER IS = 1200
