2. A block of wood 3 cm on each side has a mass of 27 g. What is the density of

the block? (Hint, don't forget to find the volume of the wood.)

1g/cm^3

Explanation:

So a block (It's a block!) of wood is 3cm on each side so it is a cube.

The volume of a cube is given by s^3. So the volume of this block is 3cm x 3cm x3 cm = 27 cm^3.

density = mass/volume = 27 g / 27 cm^3 = 1 g/cm^3.

so the answer is 1 g/cm^3.
