density = mass / volume \[volume = 0.25cm * 1.8 cm * 3.00cm\] this is the volume of the rectangular solid and beware of units density = 2.53 g /cm3 So 2.53 = m / (.25 * 1.8 * 3) m = 1.87 g hope this is what you are looking for.

\[\frac mV=\rho\] \[m=\rho\times V \]\[=2.53 \left[\frac{\text g}{{\text {cm}}^3}\right] \times 2.5[\text {cm}]\times1.80 [\text {cm}]\times3.00 [\text {cm}]\]\[=(2.53\times2.5\times1.8\times3)[\text g]\]
