Quick and dirty answer: Because they are built to be essentially hollow, they are much larger in volume than the water they displace, and so in effect they are much less dense over all than the water they displace.

Which material will float on water?
The material which are less denser than water will float on water..!!
Why is wood denser than water?
Most types of wood are not denser than water--they float in/on water. For the wood types that are denser than water, the explanation is that they contain molecules that are denser than water (e.g. resin) and the average distance between molecules is smaller.
Why would the desk float if you threw a key and a wooden desk into a lake?
the key is denser than the water the water is denser than the desk
Does a bolt float?
no because it isn't hollow and denser than water
What objects to sink or float?
An object will float if it is less dense than the water (or other liquid). If it is denser than the water, it sinks.
Why is it easier to swim in salty water than in pure water?
Salt water is denser that fresh water, so a swimmer (and ships) float higher in saltwater.
Is a marble denser than water?
Yes if it floats. Does Marble float in water? If not then the answer is no.
Which material will float on water?
The material which are less denser than water will float on water..!!
What makes an item to float or sink in water?
This depends on the density of this item: more denser than water-sink, less denser than water-float.
What will happen to a solid made from matter with a greater density than water when it is dropped into water?
The answer depends on the shape of the object. Ships, made from steel, which is denser than water, do float!
What will happen to a solid objects made from matter from with a greater density than water when it is dropped into water?
The answer depends on the shape of the object. Ships, made from steel, which is denser than water, do float!
What the density of water is equal to 1.0 gcm3. A substance with density equal to 2.1 gcm3 would in water?
Being heavier (denser) than water, it would sink.Being heavier (denser) than water, it would sink.Being heavier (denser) than water, it would sink.Being heavier (denser) than water, it would sink.
You are green put you in water you dont float what are you?
Denser than water.
Would carbon float on water?
NO, because it is denser than water
How egg float in salt water related to chemistry?
More physics than chemistry, really. Salt makes the water denser, allowing denser objects to float, than in pure water.
What will happen to a solid object made from matter with a greater density than water when it is dropped into water?
The answer depends on the shape of the object. Ships, made from steel, which is denser than water, do float!
Should a material have a higher or lower density to float in water?
A material needs a lower density than water to float in water. Ships float in water because their average density is lower than water. The average density includes the steel hull and the air inside the hull.
