The mass of an aluminum cube was measured to be (A)=71.2 g. Using
the Vernier caliper, the length of its side has measurements between
29 mm and 30 mm in the main scale and falls exactly at the (B)=28
mark on Vernier scale. From this data, what is the percent error
between the standard and experimental density of aluminum in (F)?
