For their first lab, decides to measure the density of a potato.They notice that it’s an unusual shape and floats, so it’s hard to calculate its volume.The potato’s mass is measured to be \(g\).They then cut the potato into a cube and measure that the sides of the cube have length inches, and the potato’s mass is \(g\).For a uniform density potato, the mass and volume are proportional.

(Useful conversions: 1 \(\textrm{inch}\) = 2.54 \(cm\), 1 \(cm\) = \(10^{-2}\) \(m\), 1 \(g\) = \(10^{-3}\) \(kg\)).
