Combining upper and lower bounds

Combining upper and lower bounds

Mr. Underwood

Multiple Choice

How can you calculate DENSITY ?

• volume x mass

• mass / volume

• volume / mass

• weight / area

So far you have been able to calculate the maximum and minimum values of single measurements (upper and lower bounds).

This has allowed us to calculate the error interval of a measurement e.g

However, you need to be able to calculate the maximum and minimum values of compound measurement (combining bounds together)

• The image on the right shows the rules on how to calculate maximum and minimum values of a compound measurement

• You first have to calculate the upper and lower bounds of each measurement in the calculation
