Atmospheric pressure on that day is 1.0 multiply 10 to the power of 5 Pa. calculate the total pressure at the bottom of the pond

Water pressure P=ρgh  (density X acceleration due to gravity X height of water)

                      P=1000X9.8x3=29,400 N/m2  or Pascal

But there is air pressure over water which also adds to the pressure at the bottom of the pool.

Therefore,Atmospheric pressure over the water=1.01 x 105 N/m2

So the total pressure on the bottom of the pool = 29,400+ 101000 Pa

                                                                    = 130,400 Pa
