# A cube made of an unknown material has a height of 9 cm. The mass of this cube is 3,645 grams. How do you calculate the density of this cube given this information?

$\text{Density, "rho="Mass"/"Volume}$
So given that it is a cube, $\rho = \frac{3645 \cdot g}{{\left(9 \cdot c m\right)}^{3}}$ $=$ $5 \cdot g \cdot c {m}^{-} 3$.
