You need only one to completely describe its dimensions, although you can make lots of measurements.
to make measurements
It depends on the measuring instrument that you use (including its calibration), how careful you are, how many measurements you take, whether or not you have allowed for external factors that could affect your measurement.

From a 'bespoke' tailor. He will take careful measurements and make a suit for an individual.
True
No measurements necessarily make an inch.
Your repeated careful measurements would still have precision, meaning they would consistently produce similar results when measuring the same item or quantity. While the accuracy of the measurements may be affected by not accounting for the weight of the tray, the precision would indicate that your measurements are reliable and reproducible.

Kepler's laws of planetary motion describe orbits as elliptical, with the sun at one focus. Observations over time show that the speed of Earth in its orbit varies, consistent with an elliptical shape. This, along with minor variations in distances between Earth and the sun, supports the idea of an elliptical orbit.
There is no more accurate descriptions of matter than measurements. To get the description right make your measurements precise.
