# A cube-shaped block of wood, whose edge was 3*cm long has a mass of 27*g. What is its density (rho)?

Sep 3, 2016

$\text{Density, } \rho$ $=$ $1 \cdot g \cdot c {m}^{-} 3$

#### Explanation:

$\text{Density}$ $=$ $\text{Mass"/"Volume}$

$=$ $\frac{27 \cdot g}{3 \cdot c m} ^ 3$

That is a dense block of wood. Would it float?

Typical densities of wood are $0.65 \cdot g \cdot c {m}^{-} 3$.
