yes a boat made of concrete is possible to float if it displaces water that weight more than its own weight.
This all depends on buoyancy of the liquid the boat is in, and the density (therefore the mass and volume) of the concrete boat.
The size of the boat is equal to the water displaced by the boat. This means, if the boat is bigger then its weight, the boat will float. If the boat is smaller than its weight, it sinks. This is why metal ships are so big.
Yes, they even build boats out of concrete!
Yes- because they are not a solid block of concrete- they are hollow with a large air space. The weight of the water displaced is greater than the weight of the hollow concrete hull, and it will float.
by making a boat that floats! XD
The block isn't aerodynamic, so it sinks. The boat, no matter what it's constructed with, will be able to float if it's in a shape that will be aerodynamic in water.
I can make a iron nail float. Simply melt some lead and the iron will float on top of the lead. Your question seems to be with regard to how do Boats float and the answer is Bouyancy. The Boat displaces a volume of water and if the weight of the displaced water is less than the weight of the boat, the boat will float.
What detimines whether an oject will sink or float is the amount of fluid that it displaces. If the amount of fluid displaced weighs more than the object then it will float, if it weghs less it will sink. A boat can be made of any material, even concrete.
A needle doesn't float because there is very little air in a needle. Metal is much more dense than wood, which is what most boats are made of. When a boat is made of metal, there are air stores inside of the boat that keep it afloat.
because inside the boat has air. think when u blow up a ballon it floats same with a boat the out side of the boat is metal
It can be metal and wood but it need to shape like a boat.
