Firstly you must understand that buoyancy is the very thing that allows anything to float. Buoyancy is defined as the force applied to an object by the fluid it is in, the force is quivalent to the volume of the fluid that is being displaced by that object
Example
say you have an object with a volume equal to 1 metre cubed sumbersed in water
since the object is displacing 1 m^3 of water, 1000Litres = 1 m^3 , and 1L is approximately equal to 1kg. therefore the buoyant force would be 1000 kg of force upwards.
the more fluid is displaced by an object, the more buoyant that object will be

How does an iron boat float?
Buoyancy!
What floats your boat?
There are two answers:Water provides the buoyancy necessary to float boats.Things that I enjoy doing are what "float my boat".
How can buoyancy be demonstrated?
buoyancy can be demonstrated if you float something because buoyancy is when something floats for example a boat floating in water
How do you use buoyancy?
Buoyancy is what keeps a boat floating on the top of the water. Buoyancy is what makes a helium balloon float in the air.
The upward force of a liquid or air on an object that helps it float?
The force that makes things float is called buoyancy.
What is he name of the force that helps things float?
Buoyancy
What is the name of the force that helps a ship to float?
Buoyancy
What does the hull do on a boat?
Basically, the hull on a boat keeps out the water, and displaces the water to create buoyancy, which enables the boat to float.
Does gravity allow a boat to float on water?
Without gravity, a boat wouldn't be able to float on water, so yes, gravity allows a boat to float (as well as sink into) water. A boat floats from buoyancy force. The buoyancy force is from the volume of water it displaces with it's shape below the water. The buoyancy force is equal to the volume of water it displaces multiplied by 62.4 lbs. per cubic foot (the density of water). So if the boat displaces 20 cubic feet of water with it's hull or shape it can hold 20 x 62.4 = 1248 lbs. of self weight plus cargo. Obviously there should be a factor of safety on that. In summary, a boat needs two things to float on water: Gravity and buoyancy force. Gravity keeps the boat on the water in the first place, but the buoyancy force is the actual thing that keeps the boat afloat. Technically, it is the buoyancy force that allows a boat to float, but if you want to get really technical, it is gravity in the first place that allows a boat to float on water.
How do concrete boats float?
This all depends on buoyancy of the liquid the boat is in, and the density (therefore the mass and volume) of the concrete boat.
Do material and shape affect buoyancy of a toy boat?
Yes it does because depending on the materials of the boat and how much their mass is can change the buoyancy of the toy boat. Boat can be designed to have less volume in order for it to have less density and be able to float. So if the material's mass is alot if can make the boat sink. If the material's mass is not alot then it can help the boat float. If the shape is designed to have more volume than mass it will float. If not then it will sink.
Why does a small rock sink and a boat float?
Bouyancy. A Boat/ship is hollowed out to be use to passengers, were as rocks are solid and have a lot less buoyancy.
