Question:
A block of wood has a mass of 3.67 kg and a density of 600 kg/m3. It is to be loaded with lead (1.14 x 104 kg/m3) so that it will float in water with 0.900 of its volume submerged. What mass of lead is needed if the lead is attached to?
(a) The top of the wood and
(b) The bottom of the wood?
Step by Step Answer:

Density helps us predict whether something will float. Density is super important to consider when building things like ships and submarines. The experiment in the video examines the water density by comparing a glass of water containing sugar with a simple glass of water
