How is the density of a steel ball different from a steel ship?

Density = mass/volume
let us say the mass of the steel ball and the ship are same.
but the steel ball is fully enclosed, a tight spherical volume, where as the ship is a hollow, occupies more volume (multiple times) as that of the spherical ball.
Considering the first equation, u know well the density of steel ball is much higher than the steel ship.

If something floats in water does the water have more or less density?
The general rule is that an object will float, if it has less density that the liquid (or gas) in which it is placed. If the density of a liquid is greater, a larger amount of objects will float. Also, the same object will float higher, if it is placed in a denser liquid.
What is the density of a ship if it has a mass of 4800kg and volume of 5.000.000 cm3?
Density = 0.96
What is the volume of a piece of metal?
The Volume of steel used should always be less than the volume of ship made out of it.The ratio could differ and hence there may be no specific ratio.The greater the (Ratio of Volume of ship:Ratio of Volume of steel used) say 3:1that means the ship can carry about 2 times the volume of the steel used.That means the water displaced would be 3 times volume of steel hence the water is applying the force on ship is 3 times weight of steel.***STUDY BUOYANCY
Why does the hull of a ship contain a large volume or air why?
Because the air reduces the ship's overall density, and so allows it to float.
Which floats better low density or high density substances?
Because if you look at the volume it occupies the ship will still weigh less than the same volume of water. The Greek scholar Archimedes realised when he was taking a bath what is now called his 'Law'. It is said that he ran into the street naked shouting "Eureka!" (I've found it!), although this is a legend. In his bath he realised that when an object is placed in water it experiences a force upwards (an 'upthrust') equal to the weight of water it displaces. If the upthrust is more than the weight of the object pulling downwards, the object floats. If the upwards force is too small to counteract the downwards weight of the object, it will sink. Because of its shape, even though a ship is made from dense materials, it still displaces enough water to create an upthrust larger than the weight of the ship, so it floats. However, if you somehow crushed the ship into a block, although it would weigh exactly the same, because it displaced less water, it would sink.
Why does a steel ball sink in water but a toy ship made of steel floats?
Density of a steel ball is greater than the den. Of h2o - it sinks similarly den. Of a toy ship is less than the den. Of h2o - it floats
Why will a ship of steel sink while a ship of air wont?
It's possible that a ship of steel will not sink as well. But if it will sink, it would be because the density of steel is greater then the density of water, while air's density is lower then water's.
How ship floats on water surface?
The density of the VOLUME of the ship is less than the density of the water it displaces (pushes out of the way). While the steel of a steel hulled ship is denser than water, the steel plus the air enclosed by the steel is less dense.
How can a ship made out of steel with a density much higher than the density of water float on the water?
The steel has a density greater than water; but the ship does not. To calculate density, you divide mass by volume. This includes the mass - and the volume - of any air trapped inside the ship.
Why a ship is made of steel but it can float?
In between of the steel there are other materials - like air. What counts is the average density of the ship (including empty spaces in between), not the density of its densest component.
A steel needle sinks in h20 but a steel ship floats?
The needle is solid, it's density higher than water's. The ship is hollow, its overall density lower than water's.
How steel can make a ship float?
An object will float if it has a density that is less than that of water. Or whatever liquid it is placed on. In the case of a ship, that includes not just the steel, but the entire ship - including air trapped inside the ship.
When would the density of an object float in liquid water?
The density is not directly relevant. Otherwise, ship made of steel would not float on water.
If the density of a solid is greater than that of water it sinks why then does a steel ship float in water when the density of steel is about eight times that of water?
The density of the entire ship is much less than the density of a ship-sized block of steel. That's accomplished by flattening the block of steel into a giant sheet, and then rounding the sheet on the bottom, so that it displaces much more water than the original solid block would. The final structure still has the same mass as the block of steel, but it has much more volume ... the volume of the steel, plus the additional volume of the cargo holds, the engine room, the galleys, the passenger cabins, the radio room, etc. So the original mass divided by the much greater volume winds up being a much smaller density than steel has. In fact, it winds up being smaller than the density of water.
How is the density of the floating object related to the density of the fluid it is floating in?
The "AVERAGE" Density of the entire floating object must be LESS than the density of the Fluid. The Average Density includes hollow spaces, etc. That is why a ship made of STEEL can float in water. It has a lot of EMPTY (air filled) space contained in its interior. Therefore, when the Steel Hull is immersed in the water it "DISPLACES" more water weight than the entire ship itself weighs.

How can a heave cruise ship made with lots of steel and other materials denser than water float?
That is because the ship is not pure steel. There are also spaces with air in between. This reduces the average density. Now, if the ship gets a hole, and water fills the spaces instead of air, the ship will sink.
