All depends on what you are trying to measure. Could be as simple as a tape measure/ruler where you measure 3 along 3 axes (sides) for a simple shape to a sophisticaled, calibrated laser surveying. Which ever way, it is achieved in the same way(mostly), which is measuring lengths of the object (along certain axes(as in the plural of axis, wiki cartesian coordinates if you are interested to give you some insight). Afte the lengths have been found a volume can be found. For complicated shape this has to be broken up in to smaller achievable pieces, (even most of the very sophisicated technology does this)
Alternatively if if it is to find the defining equation of the planes, it is possible to derive the volume of the object using calculus.
another option is if you are measuring a fluid you can drop something of known volume and measure the displace,ment of the fluid and that would allow you to calculate the volume
another option is ultrasonics for instance ultrasonic electromagnetic readiation is basically bounced through a material (for example a metal) and you measure the time it takes to propogate through the material,and if you know the density of the material and the length that is basically enough to be able to calculate volume also.
either way it really depends on what you are trying to measure.

What is the instrument that measures the volume of inhaled and exhaled air called?
The instrument that measures the volume of inhaled and exhaled air is called a spirometer. It is commonly used to assess lung function and diagnose respiratory conditions.

A graduated cylinder or a beaker can be used to measure the volume or capacity of a water bottle by pouring water from the bottle into the measuring instrument and reading the volume indicated on the scale.

What is the instrument that measures the volume of inhaled and exhaled air called?
The instrument that measures the volume of inhaled and exhaled air is called a spirometer. It is commonly used to assess lung function and diagnose respiratory conditions.
What instrument measures measure density?
You do the Mass of the object then, divide the Volume away from it.
What instrument measures the volume of a small stone?
A measuring cyling ( you fill it up with water then you put the stone in and the change is the volume)
What instrument measures the volume of a rectangular object?
That task can be accomplished with a ruler, a tape measure, or a measuring cup.
What instrument measures the volume of a rectangular box?
There is not an instrument designed to measure the volume of a rectangular box. You would use a ruler or tape measure or similar to measure its linear dimensions and a brain to multiply them together.
What instrument measures the volume of a square solid?
A ruler no a better way is by dropping the cube in a liquid containg beaker displaced liquid will give you the volume
What instrument measures alcohol volume?
An instrument that measures alcohol volume is called a hydrometer. It assesses the specific gravity of a liquid, which can be used to calculate the alcohol by volume (ABV) in beverages. Another common device is the alcohol meter, specifically designed for measuring the alcohol content in distilled spirits. Both instruments are essential in brewing and distillation processes.
