A The smallest unit on a ruler is 1mm. Two students measured the width of a wooden
block and recorded them as 5.25 cm and 5.27 cm.Analyze the data gathered Are
these two equally precise? Comment.
5 Can measurements be accurate but not precise? Justify your answer by citing a
specific example.
6 Two students, John and Jay are given a small cylinder of aluminium of known mass and
asked to determine its density. (The 'accepted' density of aluminium is 2.702 g/cm)
Since density is mass/volume, the students need to calculate the volume of the cylinder
The height and diameter of the cylinder need to be measured in order to calculate its
volume
