Question

If steel is more dense than lake water, why can a boat float? the average density of the boat, including the steel and air, is less dense than 1.00 g/cm³. the average density of the boat, including the steel and air, is more dense than 1.00 g/cm³. lake water is more dense than pure water. steel has a special ability to float regardless of density.

Answer 1

Or The average density of the boat, including the steel and air, is less dense than 1.00 g/cm³..

Answer 2

Answer;

The average density of the boat, including the steel and air, is less dense than 1.00 g/cm³.

Explanation;

• The average density of an object determines whether the object sinks or floats.  Therefore the average density determines whether the boat will sink or float on water.
• Reducing the average density makes a steel boat float on water.  Additionally making steel hollow also makes a boat float as this expands its volume  without changing its mass.  
• Steel is strong, but it is quite easy to reduce the average density of a boat to less than the density of water by making the shell of the boat very thin hence making if float.
