"This is not a trick question. This is a real math problem so don't say that a bus has no legs. And don't include a bus driver!

Read carefully:

There are 7 girls in a bus.
Each girl has 7 backpacks.

In each backpack, there are 7 big cats.

For every big cat there are 7 little cats.

Question: How many legs are there in the bus? Please show working."
