Length is measured with a ruler, or any kind of object with measurements on it.
Volume is measured in two ways:
If it's a liquid, it is poured into a container with measurements on it.
If it's a solid, it is completely submerged into a container filled with a liquid (usually water) and using the measurements on the side of the container, all that needs to be done is to measure the difference to find the volume.
Mass is weight/volume.
Density in some cases is weight/mass, but it is mostly volume/mass.
Hope this is what you wanted!
Scientists use the concept of density to measure how much stuff (mass) is in a specified volume of a substance. Density is calculated by dividing the mass of the substance by its volume. This provides a measure of how tightly packed the particles are within the substance.
The answer depends on what characteristic you wish to measure: its length, base area, volume, mass, density, optical density, temperature, and so on.

Scientists typically use the method of mass/volume, where they measure the mass of a substance and divide it by the volume it occupies. This ratio gives the density of the substance, expressed in units like grams per cubic centimeter. By knowing the density and volume, scientists can calculate the amount of substance within a specified volume accurately.
Weigh the material in pounds. Then measure the length, width and height. Do this in feet. Calculate the volume by multiplying length x width x height = Volume. Volume = length x width x height Divide the weight by the volume: Weight / Volume Density = Weight / Volume Your density is in units of lbs per cubic foot
The density of a metal can be measured by dividing its mass by its volume. The formula for density is density = mass/volume. This can be done by weighing the metal to find its mass and then calculating its volume using measurements such as length, width, and height.
Density is defined as the mass divided by the volume. This definition can, in many cases, also be used to measure the density.
That depends what you want to measure: length, width, volume, weight, mass, density, etc.
The answer depends on what you want to measure: its mass, length, "equatorial" circumference, volume, density, temperature, conductivity, ...
