A block of wood, with density 828 kg/m3 , has a cubic shape with sides 0.340 m long. A rope of negligible mass is used to tie a piece of lead to the bottom of the wood. The lead pulls the wood into the water until it is just completely covered with water. What is the mass of the lead? [Hint: Don't forget to consider the buoyant force on both the wood and the lead.]
Kg?
Since d=m/v do i multiply 0.340m or 0.340m^3 because its a cube by 828?
