Yes. It is called a T.A.R.D.I.S. (Time And Relative Dimensions In Space.) It is a blue telephone box on the outside.
You can see which has the largest spread of data.... Where the extreme values lie... The bigger the box the wider the spread of half of the data... and vice versa
It depends. Some are a cm and other's are bigger. Most commonly it's a cm by cm.
If you're not going to tell us what numbers are in the box, we can't help you.

No riding the sluice box!
sluice box, long tom, pan, rocker, panning, digging, mining, hydraulic mining
There are many ways a sluice box traps gold. A sluice box traps gold by doing something called fine dropping the gold to collect it in the easiest and fastest way possible.
With river water. Most of the gold was found in rivers or near rivers so panning was used along with a sluice box or rocker. These would wash the gold from the dirt ( gold is heavier than dirt so it would stay in the wire or at the bottom of the pan/box).

Edward Hargraves invented the rocker box
a wooden box used to separate the gold from the rubble
A rocker and cradle gets its name from its method of operation. Simply, a rocker consists of a sluice box and hopper mounted in such a way that it can rock side to side. Gold bearing gravel is dropped into the hopper which was typically a square shallow box with a metal or wooden screen on the bottom. A miner would then pour water into the hopper. The smaller gravel would pass through the screen and drop into the sluice as the miner continued to pour water into the hopper. The miner would also rock the rocker from side to side. This helped the gold to settle to the bottom of the sluice where it would get caught in the riffles. Once all of the small gravel had passed through the hopper screen, the miner would remove the hopper and dump out the larger rocks after checking visually for larger nuggets. Rockers were popular because they did not require as large of a water supply as was needed to run a regular sluice. Regular sluices needed a good flow of moving water to wash out the gold bearing gravel.
If you want to go sluicing for gold then you need a sluice box
Simply anyone who wants to use it.
It was an easy method to find gold. All a man needed was a gold pan, and find a spot on the river to pan. Some got a bit more fancy with a sluice box or rocker to seek gold.
