Question

The density of oak is .710 g/cm^3 and the density of pine is .373 g/cm^3. If you had a 1 kg block of each kind of wood, which block would be larger?

Answer 1

Density is mass per unit of volume. That is, how much mass is in each \(cm^3\) or whatever volume you use.

Some materials are very dense, like cannonballs. Others are less dense, like cotton balls.

Let's compare a more dense object with a less dense object.
Picture the cannonball in your mind.
You'd need a lot of cotton to have the same mass.

Likewise,
Picture a cotton ball in your mind.
A piece of a cannonball would have to be much smaller to have the same mass.

Now to your problem. Oak has a higher density than pine.
Oak is high density, like a the cannonball.
Pine is low density, like the cotton.

Which will you need more of to get the same mass?

Answer 2

Pine & thanks for making it clear in practical application

Answer 3

Yeah! Thanks, and you're welcome!
