Measure of box reported by Cristal = 18 cubic units
Measure of box reported by Kyle = 48 cubic units
To find: The reason behind the discrepancies in their reporting.
Answer:
The measurement has been done in 'cubic units'. This indicates that they are measuring the volume of the box. Now, the differences in their reporting can be due to the following reasons:
Unit of measurement: Cristal might have reported in imperial units whereas Kyle must have used metric units. Example, an inch is greater than a centimeter.
Instrument used for measurement: Either Cristal or Kyle are using a non-standardized instrument for recording measurements. The unit spacing between, say Kyle's instrument might be smaller than that of Cristal's. They need to check it against a standard ruler to standardize their rulers.
Least count error: Instruments with a greater least count or bigger gradations are prone to errors than instruments with a smaller least count. Example, a ruler with a least count of 1 inch will not be able to record in decimal units whereas a ruler with a least count of 1 mm can make fine recording.
Rigidity of box: If the box can shrink under different environmental conditions then there will inconsistencies in their recording. Cristal must have recorded its volume in cold temperature whereas Kyle must have recorded its volume in hot temperature. (<em>sounds odd but is true</em>)
Scientists use all sorts of different discoveries to help date-back the day Earth was created. Some of these include types of rock, fossils, trees, chemicals in water, minerals, and elements.
Answer: The Chesapeake Bay is the largest estuary in the United States. The bay provides vitally important habitats for wildlife, lots of recreational opportunities for people, and is an important fishery upon which both people and wildlife depend.
