# What is the density of a rock that has a mass of 234 g and a volume of 7.9 cm^3?

$\rho$ $\left(\text{density}\right)$ $\approx$ $30 \cdot g \cdot c {m}^{-} 3$
$\rho$ $\left(\text{density}\right)$ $=$ $\text{Mass"/"Volume}$ $=$ $\frac{234 \cdot g}{7.9 \cdot c {m}^{-} 3}$ $=$ ?? $g \cdot c {m}^{-} 3$.
