Bigger, Smaller or the same?

We noticed that the school milk containers are a different shape. We wondered if they contained the same amount of milk.



We measured the length, height and width of each milk carton and then we multiplied the numbers to get the volumne of each carton. The old carton holds about 215ml and the new one about 218ml.

The only problem with the new boxes is that they are harder to stack because they are taller.
