The canoe gliding gracefully along the water in the photograph is made of concrete, which has a density of about Explain why the canoe does not sink.
The density of the canoe is determined by the density of the concrete and the density of the hollow space inside the canoe, where the passengers sit. It is the hollow space, (filled with air), that makes the density of the canoe less than that of water (1.0 g/cm3).
If the concrete canoe fills with water, it will sink to the bottom, unlike a wooden canoe.
Concrete canoe's density comes from concrete and hollow space, making it less dense than water. If filled, it sinks.
