Answer 1

Answer:

The answer is

0.4 g/cm³

Explanation:

The density of a substance can be found by using the formula

$density = \frac{mass}{volume}$

From the question

mass of wood = 120 g

volume = 300 cm³

So the density of the wood is

$density = \frac{120}{300} \\ = \frac{12}{30} = \frac{2}{5}$

We have the final answer as

0.4 g/cm³

Hope this helps you
