It all depends upon the shape of the object. For example, the volume of a rectangular prism is lengthxwidthxheight. For an irregular shaped object, one strategy is to immerse the object into a measured amount of water, then measure what is the total volume of water plus object, and subtract the original volume of water.
no
mass/volume
Use the formula for a cylinder.
For mass you use a triple-beam balance and for volume you use a graduated cylinder
The volume of water displaced is equal to the volume of the object submerged into the water
i dont know? maybe you can use yahoo....
mass/volume
density= mass/volume
Use Boyle's law
You can use the formula for a cylinder in this case.
The best strategy in that situation would be to use what you do know.
For mass, you would use a triple-beam balance. For volume, you would either use a graduated cylinder (for liquids), calculate the displacement with a graduated cylinder (for an odd-shaped solid), or calculate it using the equation for volume (for a regularly-shaped solid).
