If steel is more dense than lake water, why can a boat float?

The shape of boat allows the boat to have an average density less than one and also causes displacement of water in large amount.

Explanation:

The floating of an object is governed by Archimedes principle which states that the amount of water displaced by an object when it is placed in water must be large enough to allow the object to float.

When the steel metal is carved into a boat, its shape and surface area changes due to which it displaces a larger volume of water thereby causing the boat to float. Also the average density of boat as compared to its surrounding water gets lesser than unit g/cm^3 which also causes floating of steel boat in lake water.

prism b but im not for sure

i was thinking 4.0 v hope this
