Answer:
<h2>Density = 0.75 g/cm³</h2>
Explanation:
Density of a substance is given by
<h3>
</h3>
From the question
mass of the wood = 180 g
Since the wood is a cuboid we can find the volume using the formula
Volume = length × width × height
From the question
length = 10cm
width = 6 cm
height = 4 cm
Volume = 10 × 6 × 4 = 240 cm³
Substitute the values into the above formula and solve for the Density
That's
<h3>
</h3>
We have the final answer as
<h3>Density = 0.75 g/cm³</h3>
