$\mathbf{a.\ 0.015\text{ g/cm}^3}$

Step-by-step explanation:

Formula for density = $\dfrac{\text{Mass}}{\text{Volume}}$

As per given , dimensions of a rectangular piece of wood:

Length: 25 cm. Width: 10 cm. Height: 4 cm.

Mass: 15 g

Volume of rectangular piece = Length x width x height

= 25 x 10 x 4 = 1000 cubic cm

Now , density = $\dfrac{15}{1000}=0.015\text{ g/cm}^3$

Hence, the correct option is $\mathbf{a.\ 0.015\text{ g/cm}^3}$
