# What is the density of a block that has the dimensions of 2.5 cm, 3.2 cm, and 5.4 cm, and a mass of 6.38 g?

Density is simply mass per unit volume, which has the dimensions $g \cdot c {m}^{-} 3$
$\text{Density} , \rho$ $=$ $\frac{6.38 \cdot g}{2.5 \cdot c m \times 3.2 \cdot c m \times 5.4 \cdot c m}$ $=$ ?? g*cm^-3.
