(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A swimming pool has dimensions 28.0 m 12.0 m and a flat bottom. When the pool is filled to a depth of 2.10 m with fresh water, what is the force caused by the water on the bottom?

On each end? (The ends are 12.0 m.)

On each side? (The sides are 28.0 m.)

2. Relevant equations

d = density

P = dgV

P = F/A

3. The attempt at a solution

I got my first answer and it was solved by using the above equation

(28.0)(12.0)(2.10)m^{3}x (1000) kg/m^{3}x 9.80 m/s^{2}

= 6914880 N

for each end I am using

(12.0)(2.10)m^{2}x (9.80)m/s^{2}x (1000) kg/m^{3}=

which comes around to 246960

It wants the answers in kN and it says my answer is within 10% of the correct answer. I did the same for the third part of the problem and got the same response. I even looked at the solutions manual and they seemed to follow the same procedure so I am not sure what I am doing wrong.
