Accurate linear measurement.
The answer depends on the size of the cube: it could be a micrometre, vernier callipers, a ruler, a tape measure.
by dividing diameter by 2 :)
It depends on what you are trying to measure. If you are measuring the length of a car, for example, any reading obtained using vernier callipers is likely to be totally useless. The key is to select a tool that is appropriate to the task.
A rulerDepending on the degree of accuracy required: a ruler, vernier callipers, micrometer.
vernier-caliper
Because they were invented by Pierre Vernier in 1631.
I would use vernier callipers.
To measure things, or is that just too obvious? A.K.A. Vernier Callipers
Measure the length of its side - using vernier callipers for accuracy - and cube the result.
