Will the precision of a calculation (ex. volume = l x w x h) ever be more precise than the original measurements (ex. length)? explain your answer.

When it comes to measurements and calculations, two terms always come into play: precision and accuracy. By definition, precision is the closeness of the measurements or calculations of your repeated trials with each other. On the other hand, accuracy is the closeness of a measurement to the known or exact value.

Suppose you want to measure the volume of your cube. You start by measuring the side of the cube. Your two measurement are 6.50 inches and 6.45 inches. These two measurements are precise because they only differ by 0.05 inches. Now, if you calculate their volumes, that would be 274.625 and 268.336 cubic inches, respectively. Notice that the volume measurements differ greatly relative to the side measurements. This proves that it is always more precise to use the original measurements. Because they are raw, their differences are not magnified by calculations.

B. nuclear reactions could first occur.

Answer it was we, the the whole people, who formed the union. and we formed it, not to give the blessings of liberty, but to secure them: not to the half of ourselves and the half of our posterity, but to the whole people- women as well as men.
