Consider a cubical tank of side $2 \mathrm{~m}$ with its top open. It is filled with water up to a height of $1 \mathrm{~m} .$ Assuming the density of water to be $1000 \mathrm{~kg} / \mathrm{m}^{3}, g$ as $9.81 \mathrm{~m} / \mathrm{s}^{2}$ and the atmospheric pressure to be $100 \mathrm{kPa}$, the net hydrostatic force (in kN) on the side face of the tank due to the air and water is____________(accurate to two decimal places)
