A piece of wood has a mass of 8g and a volume of 10cm³ work out the density of the wood

olchik [2.2K]

Answer:

<h2>0.8 g/cm³</h2>

Explanation:

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

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

From the question

mass = 8 g

volume = 10 cm³

We have

$density = \frac{8}{10} = \frac{4}{5} = 0.8 \\$

We have the final answer as

<h3>0.8 g/cm³</h3>
