If it is a cube shape, only a ruler is needed. Measure height, width and length, then multiply the three.
You could practically find the volume by submerging it into a full container of liquid and measure how much of it overflows/is displaced.
you wouldn't really use an instrument, just the formula to get the answer...
say a square was 6x6x6 you would just times length-height-width to get you answer
therefore the square would have the volume of:
216cm cubed
A graduated cylinder or other container filled with liquid or sand can be used to measure volume,
by measuring the change or displacement in its volume.
When submerged in a filled container, an object will displace its volume. When placed in a filled container, it will only displace its weight in liquid, and may float.

A metre stick
A measuring cup is best.

The water displacement method is typically used to find the volume of an irregular solid. The object is submerged in a known amount of water, and the increase in water volume is measured. This increase in volume is equal to the volume of the irregular solid.
Eureka Can
There kind of solid object will determine the formula that will be used to find its volume.
width, length, and height
Water Displacement technique
Liquid displacement
Archimedes' principle is used. Water will be displaced by the volume of what is put into it. That displaced volume can be measured giving the weight.
