Question

A water storage tank measures 2m*1.5m*2m and contains water to a depth of 1.6m.given that the pressure exerted by 1m of water is 9.81 kN/m2, which of the follwing calcultions shows how the total pressure exerted on the tank should be calculated

Answer 1

Oh if only there was yahoo answers when I was taking physics in high school.  Well I won't do your homework for you but I'll steer you on the right path.  Also I can't finish the answer because I don't see what options you have for the "which of the following" part.

I assume you're talking about the pressure exerted on the bottom of the tank, as if it were sitting on a scale.

Think of the pressure being exerted as the weight of water distributed across the bottom of the tank.  In fact, the units they give you, kN divided by m^2 gives you the biggest hint you need.
