3. Two students are arguing about their skill in determining the volume of a cube of iron (which has an accepted density value of 7.87 g/cm'). One student believes he will be able to take a better volume
using the formula = lxwx h. His volume is 4,59 cm'. The other student believes she can find a better
volume using water displacement. Her volume is 4.73 cm”. The mass of the iron cube is 37.0 g. Find the
percent error for each and determine which student had the best measurement,
