1. The problem statement, all variables and given/known data A rectangular bar of soap floats with 3.5 cm extending below the water surface and 1.5 cm above. what is its density? 2. Relevant equations p(rho)=m/v 3. The attempt at a solution I dont know how to compute the volume since we are given only two lengths. Athough, i think a better way to approach this problem will be with buoyancy. To start,can we consider this block to be in equilibrium since it is floating? I am confused because it is also partially submerged.
