# A rectangular block of copper metal weighs 1866 g. The dimensions of the block are 8.4 cm by 5.5 cm by 4.6 cm. From this data, what is the density of copper?

$\rho ,$ $\text{density}$ $=$ $\text{Mass"/"Volume}$ $=$ ??*g*cm^-3

#### Explanation:

And we can calculate the density from these data:

So here, ${\rho}_{\text{copper}}$ $=$ $\frac{1866 \cdot g}{8.4 \cdot c m \times 5.5 \cdot c m \times 4.6 \cdot c m}$

$=$ $8.7 \cdot g \cdot c {m}^{-} 3$

This also gives you the appropriate dimensions, $g \cdot c {m}^{-} 3$.
