A student is trying to identify the composition of a pure metal block by determining its density. The student records the mass of the sample to be $25\mathrm{.}0$ g$.$ The rectangular block is $2\mathrm{.}00$ cm $\backslash$times $3\mathrm{.}00$ cm $\backslash$times $1\mathrm{.}40$ cm$.$ Calculate the density $($in g$/$cm$3).$ Express your answer to the correct number of significant figures.
