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.

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

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.

Simple multiply 45 units by $0.99you'll get $44.55
