Homework Statement
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
Homework Equations
P=pgh
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?
