Question

A block of wood has the mass of 180 grams. It is 10cm long, 6cm wide and

4cm thick. What is its density?

Answer 1

`.75g/cm^3`

Explanation:

density = mass / volume

We already know the mass - 180g

Find the volume

`10cm * 6cm * 4cm = 240 cm^(3)`

Plug in the volume and mass in the density formula

`density = 180g / 240cm^(3)`

Simplify

`Density = .75g/cm^(3)`
