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 $$g$$ = $$10^{-3}$$ $$kg$$).
