Want this question answered?
Usually you can use one of the well-known formulae, for example the volume of a sphere, of a pyramid, etc.
If an object sinks in a fluid then it has a density greater than the fluid. This assumes the object is solid and not shaped like a boat.
If the shape of the object is regular (a cube or a sphere) then the volume can be calculated from the measurement of the object's key dimension(s). And the object's mass can be determined in a mass balance. Give the mass and volume the density is calculated by dividing the mass by the volume. Where the object's shape is irregular, the volume may be determined by measuring the volume of a liquid displaced by submerging the object completely in that liquid.
Measure the volume of the object which is same as the volume of the displaced liquid in which that sinks. And measure the mass of the same object from a weighing machine. then use density = mass/volume
No. The key to whether an object floats or sinks is the average density, i.e., mass divided by volume. Also, whether an object will float or not also strictly depends on the surface volume. A piece of tin foil shaped into a boat will float and the same mass of tin foil shaped into a crumpled up ball will not float.
conclusion
density=mass/volume Thtas how dez equations are found.
think of something ya self cheater
I am not positive but i think that a regular shaped object can be measured and an irregular can not Hope this helps :D
First you get the object mass by weighing it.Then you get its volume by immersing it in a scaled water container and see the increase in water volume which gives the object volume.Then you divide the mass by the volume to get the object density.
Force it below the surface of water and measure the force required.
The same units are used for regular or irregular objects - for example, kilogram per cubic meter.
Mass divided by Volume = Density. Or use the displacement method for an irregularly shaped object.
Depends on the shape. Basically, multiply the length times the width times the height, but there are many ways to do that.
