Answer:

The right solution is "2625 kN".

Explanation:

According to the question,

The average pressure will be:

= [tex]density\times g\times \frac{h}{2}[/tex]

By putting values, we get

= [tex]1000\times 9.8\times \frac{12.2}{2}[/tex]

= [tex]1000\times 9.8\times 6.1[/tex]

= [tex]59780[/tex]

hence,

The average force will be:

= [tex]Pressure\times Area[/tex]

= [tex]59780\times 3.6\times 12.2[/tex]

= [tex]2625537 \ N[/tex]

Or,

= [tex]2625 \ kN[/tex]
