Physical Experiment Report "Measure the Volume of Irregular Objects"

Mass m = density p × volume v
Put the object into the water, measure the rising extent of the water surface, or put it into a full measuring cylinder, measure the volume of the overflowing water, indirectly obtain the volume of the part of the object immersed in the water and then cut the object along the level surface, remove it, use The balance measures the mass of the underwater part.
Calculate its density by the formula.
Then measure the mass of the whole object as a whole by v=m/p
Calculate the total volume.

Take a measuring cup, the water surface is flush with the cup surface, and find a way to immerse the object in the water and weigh the volume of the overflowing water.

If the container is cylindrical, fill it with water, then put the object into the water and remove the object. The hollow part of the container is the volume of this object.
The area of ​​the cylinder = the bottom area × height If the object does not sink, put an iron block on the object into the water, measure the volume of the iron block and the object, and then measure the volume of the iron block, and then use the whole volume of the volume to reduce The volume of the iron block is the volume of the object.

An object that is soluble in water is measured by a liquid that is incompatible with the object. The object that is not sinking is measured by a liquid having a lower density than the physical one.
