What is the answer to unlock the excel sheet?

Question

There are 7 girls on 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?
 The number of legs is the password to unlock the Excel sheet. If you  open
it, add your name and send it on to see who else can unlock it.
 Send it back to let the person know you got it correct. This is a real
math problem!

 

Answer 1

There are 7 girls on a bus                 7*2=14
 Each girl has 7 backpacks
 In each backpack, there are 7 big cats            7* 7*7=343*4=1372
 For every big cat there are 7 little cats           7*7*7*7=2401*4=9604

Total number of legs=14+1372+9604=10990

See if this works and let me know?
