Such an instrument could be called the Laser Scan Micrometer.
He wanted an instrument he could hoist.
One could use a ruler.
The instrument you would use could be a beaker or a graduated cylinder.
a bathroom scale
seismograph is one instrument that could measure earthquakes and volcanoes etc but seismograph is many times use at earthquake!
The most direct way to measure the angle of a hill would be to use a clinomiter. You could also use a level and staff.
A ruler is an example of an instrument that can be used to measure relatively small linear distances, though it could not measure all three at once.
We could use a laboratory scale to measure a mole of solid material. A mole represents Avogadro's number of atoms or molecules of the solid material. Table salt, sodium chloride, for instance has a weight of 58.44277 grams per mole. The scale in the chemistry lab would be the instrument to use to measure that and to measure out a mole of most other solids.
the answer is 10 years a scientist wanted to see how long they could stay without going crazy
If you have a ruler then you could measure the length width and height and then multiply them together. (LWH is the formula)
I would call it 10^84 as would any mathematician or scientist who wanted to communicate. However, if you wanted to obfuscate and annoy your audience or be pretentious, you could say vigintiseptillion.
