Good maths skills! The room has a volume of \(5000 \, \mathrm{litres}\). Each human has a volume of \(50 \, \mathrm{litres}\) So, the room can fit \(\frac{5000}{50} = 100\) humans.
So, when we say matter in Science, we mean things that have a mass and volume.
Which of the following is an example of matter?
  • Oxygen in the atmosphere
  • Friendship between the monkey and the giraffe
  • Both
  • Neither
