1. The problem statement, all variables and given/known data Refer to Figure 3. A steel box (250 mm x 250 mm x 250 mm) is placed at the bottom of a tank. If the pressure on the top surface is 10000 Pa, what is the water depth in the tank? Answer a. 1019 mm b. 251.02 mm c. 1269 mm water density: 1000 kg/m3 gravity: 9.81 2. Relevant equations P=pgh 3. The attempt at a solution if the pressure on the top surface f the box is 10,000pa, then by rearranging the formulae P=pgh you get: 10,000= 1000 x 9.81 x h solving for h: h = 0.981 meters adding the depth at the top of the box to the height of the box to find the final depth of the tank= 981mm + 250mm = 1231mm however this is not the correct answer?
