WebRemember that all uncertainty estimates (calculated or otherwise) are estimatesgood only to about one significant figure. Do notwaste a lot of time trying to calculate the uncertainty exactly: use the range method (unless you really need the greater accuracy of the formal method). EXERCISES Exercise 11.1 WebAug 27, 2010 · Solution. Let x, y and z be the box’s length, width and height, respectively, and the uncertainties be Δ x, Δ y, Δ z. Since V = x·y·z, we can use Eqn. 1 to determine the uncertainty in the volume ( Δ V), which results in Eqn. 4. We know that , and , and can then make these substitutions in Eqn. 4 to give Eqn. 5.
