1. The problem statement, all variables and given/known data A 9 cm square wooden post (density=420kg/m3) is 1.3m long and floats in sweater (density=1029 kg/m3. How deep is the post submerged in the water? The picture shows a 9cm x 9cm cross section of the post. 2. Relevant equations Fb=density of liquid x volume of liquid submerged x gravity Fmg=density of post x volume of post x gravity P=density x gravity x height P=Force/area 3. The attempt at a solution I first found the force mg. 420 x (.09x.09x1.3) x 9.8=.103194 N Then I found pressure P=.103194/ (.09x.09)=12.74 I don't think this is right, and I am unsure where to next. Can anyone help me understand how I should be doing this?
