How do you experimentally determine the volume of an irregularly shaped object that floats?

Personally, what I would do would be to experimentally find a lead fishing sinker,
rock, gold coin etc., which, when added to the irregular object, sinks them both.
For accuracy, the object selected should be smaller than the irregular object.
The smaller, the better.
Then, in the usual way, find the volume of the sinker, the rock, or the gold coin alone.
Write it down so I don't forget it.
Finally, glue the 'ballast' to the irregular object, and measure the volume of the
combination by sinking it. From the volume I find, subtract the volume of the
ballast alone, and I'll have the volume of the irregular object.

In that case the math would be...
F₀ = force or weight in air (upwards)
F₁ = force or weight submerged (upwards)
ρ = density of water.
V = volume of object
(F₀-F₁)= (mass of water displaced) x g = ρV x g
By submerging the scale used to measure the force or by using a pulling and string (if you what to keep scale dry) you would find that F₁ is down instead of up. This simply means that the value F₁ in the above equation is negative instead of positive.
You would use the same equation.
To help explain let...
ρ₀ = density of object
ρ₂ = density of water displaced
ρ₁ = effective density of object when is it submerged.
ρ₁= ρ₀-ρ₂
If ρ₀ is greater than ρ₂ the object sinks and ρ₁ is positive.
If ρ₀ is less than than ρ₂ the object floats and ρ₁ is negative.

How could you determine if an object has greater density than water?
It will sink when you put it in water. If it floats it has less density then water.
How do you determine the volume of an irregularly shaped object like a mineral?
Submerge the object in a known volume of liquid within a container with graduation markings. Carefully turn the object to release and trapped gases from concavities. Measure the new volume of liquid with the object submerged and subtract the original volume. The difference is the volume of the irregularly shaped object. If the object is buoyant, choose a lower density liquid or hold the object beneath the surface with a rod or rods, noting the length of rod(s) submerged at the time of the second fluid measurement, then subtract the volume of rod submerged from the difference in the two fluid volumes.
Which property of an object will never affect whether the object sinks or floats?
Color
How can you calculate the volume of an irregularly shaped object?
If the object in question is water proof, and small enough. You can measure the amount of displaced water when it is placed in a tank full of water, this may not work for a lot of things but it can help when attempting to measure some objects.
When an object floats the buoyant force is what the weight of the object?
If the object is floating, then the buoyant force is equal to the object's weight.
How do you determine the volume of an irregularly shaped object that floats?
You can push it under water / under the liquid's surface, and measure the displacement of liquid.
What part on an object will determine whether it floats?
it is not a part it is the bouancy of the material
What two forces determine whether an object floats or sinks?
Buoyancy and pressure determine whether the object floats or sinks.
What method should you use to determine the volume of an irregularly shaped object?
Google "Archimedes' Principle" and see if that gives you a clue...
How do you determine if an object floats or sinks in water?
If the object is less dense than water it will float, but if it is more dense it will sink.
How would knowing the density of different substances be useful?
it can determine if an object sinks or floats in the substance
Does the bouyant force on a submerged object depend on the weight of the object?
No, but the difference between the buoyant force and the weight of the object will determine whether it floats or sinks.
How do you use the displacement method to find the volume of an irregularly shaped object?
Half fill a graduated glass beaker with water and note the level. Place irregularly shaped object into the beaker. Note the new level. The difference between the two levels is the volume of the object. cw: OK, that method works for objects that don't get wet -- like steel. Tissue paper would not be a good candidate. Also, if the object floats, you have to submerge the object.
How does an object's density determine whether it floats or sinks?
An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
How could you determine if an object has greater density than water?
It will sink when you put it in water. If it floats it has less density then water.
When an object floats what does the object have?
when a object float it has density
What piece of lab equipment would you use to determine the volume of an irregularly shaped object?
A beaker. Simply fill the beaker with a known quantity of liquid. Drop the object into the beaker, and measure the difference in the fluid levels.
