You have a piece of balsa wood that is 45 cm long, 8 cm high, and 4 cm wide. It weighs 50 g. What is its density?

$\text{Density}$ $\cong$ $0.03 \cdot g \cdot c {m}^{-} 3$

Explanation:

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

$\rho$ $=$ $\frac{50 \cdot g}{45 \cdot c m \times 8 \cdot c m \times 4 \cdot c m}$ $=$ $\frac{50 \cdot g}{1440 \cdot c {m}^{3}}$

$=$ ??*g*cm^-3.

So will balsa wood float? Why or why not?
