There is no generic name for such objects but I can give you some specific examples:-
Pumice
Styrofoam
Gases
The planet Saturn (which if you could do it would float on water).
Another name for the ratio of mass to volume is density. Density is calculated by dividing an object's mass by its volume. It is a measure of how much mass is contained in a given volume.
The technique used to measure the volume of irregular objects is called water displacement. It involves submerging the object in a container of water and measuring the volume of water displaced by the object. This volume is equal to the volume of the object.
The method of finding the volume of an object with an irregular shape is called displacement method or water displacement method. This method involves submerging the irregular object in water and measuring the volume of water displaced to determine the object's volume.
Another name for displacement can is overload can. They are used to measure the volume of a solid object by submerging it in water and measuring the volume of water displaced.
The method is called water displacement method. This technique involves measuring the volume of water displaced by an irregular object when it is submerged in a container of water.
Another name for the ratio of mass to volume is density. Density is calculated by dividing an object's mass by its volume. It is a measure of how much mass is contained in a given volume.
The scientific name for density is mass per unit volume. It is typically denoted by the symbol "ρ" (rho) and is calculated by dividing an object's mass by its volume.
Mass per unit of volume is the most common way to measure density, which shows how close the particles, molecules, and atoms are to each other. Therefore, it can be found by taking a certain amount of space (volume) and dividing it by how many atoms (mass) can be found in it.
Density of an object is measured in g/cm³. The equation is D=M/V, D being the density of the object, M being the mass of the object, and V being the volume of the object. Also when its dealing with a liquid the unit is g/ml.
The technique used to measure the volume of irregular objects is called water displacement. It involves submerging the object in a container of water and measuring the volume of water displaced by the object. This volume is equal to the volume of the object.
Displacement
The method of finding the volume of an object with an irregular shape is called displacement method or water displacement method. This method involves submerging the irregular object in water and measuring the volume of water displaced to determine the object's volume.
volume
Density is a measure of how much mass is contained in a given volume. It is calculated by dividing an object's mass by its volume. The unit of density is typically expressed in kilograms per cubic meter (kg/m³) for the metric system.
The name of the procedure to find the volume of an irregular object is calleD water displacement. You can do this by using a graduated cylinder. so say you fill the graduate up to 50ML and then you drop the object in and it is 100ML . so that tells you the volume of the object is 50ML because you subtract 100ML - 50ML = 50ML
Displacement method.... Is the method to find volume of an irregular object
The method used to find the volume of a regular object is typically called the "displacement method" or "calculating volume by measuring dimensions". This involves measuring the length, width, and height of the object and then multiplying these dimensions together to find the volume.
