1. The problem statement, all variables and given/known data 2. Relevant equations density = mass/volume FB = rhoo vog for a floating object F = mg 3. The attempt at a solution Buoyant force = force of gravity due to the board rhoo vo = m vo = area*height submerged vo = 2.4*.05 vo = 0.12 m^3 volume of the board = thickness*area = 0.15*2.4 = 0.36 m^3 To find the density of the board, I need to know the mass of the board. I tried using the buoyant force of a floating object, but I need the density of the object. Any help?
