# Data Processing Quiz

## Make sure to try these on a piece of paper first

This question is based on the legend of how Archimedes sat in a bath tube and noticed that his body mass displaced a certain volume of water. He had his famous ‘Eureka’ moment and is said to have ran down the streets of ancient Greece naked because he was so amazed!

A piece of metal with a mass of 21.621g was placed in 38.6 $latex cm^{3}$ of water in a measuring cylinder.

The water level was seen to rise to 42.3 $latex cm^{3}$. From this data, the best value that one can report for the density of this metal is:

A. 7.207 g/$latex cm^{3}$

B. 7.21 g/$latex cm^{3}$

C. 8.45 g/$latex cm^{3}$

D. 7.2 g/$latex cm^{3}$
