# How many legs?

My brother sent me this little mathematical puzzle this morning (the answer would unlock an Excel file but I won't post that here cause it was just an illustration of the solution).

Here goes:

In a bus are 7 small girls. Each girl has 7 bags. In each bag are 7 cats and each cat has 7 kittens. Each cat has 4 legs. How many legs in total are on the bus?

Write your answer in a comment and I'll let you know if you're right or wrong :-)

EDIT: Just accept that everything written above is true. There are no sneaky tricks or anything like that. All I need is the total number of legs on the bus given all the above :-)
