If you have calibrated eyeballs
in order to get the result in mm or cm
A metal tape which contains diameter graduations along the tape is wrapped aroud the groove in asheave.this tape has space apart supports which precisely position the tape at acertain depth in the groove.When the two ends of the tape intersects,there we find the diameter of the groove and it has a vernier graduation.
They're actually many but I'll just mention 5 for each nationalities.1. BRITISH MATHEMATICIANS* John Adair* John Craig* James Gregory (or James Gregorie)* William Jones* Thomas Rudd2. ENGLISH MATHEMATICIANS* Thomas Allen* Robert Anderson* John Babington* Robert Wood* Isaac Newton3. FRENCH MATHEMATICIANS* Pierre Vernier* Antoine Gombaud* Jean de Beaugrand* Marie Crous* Blaise Pascal4.

Measure the length of its side - using vernier callipers for accuracy - and cube the result.
by dividing diameter by 2 :)
Because they were invented by Pierre Vernier in 1631.
I would use vernier callipers.
A rulerDepending on the degree of accuracy required: a ruler, vernier callipers, micrometer.
Outer jaws are used. Inner jaws will be use to find the inner dia of the cylindrical vessel.
To measure things, or is that just too obvious? A.K.A. Vernier Callipers
0.1mm It is the range of verniercalliper. As it has least count 0.1mm that's why its range is 0.1 mm in physics laboratory
