A friend sent me this math promblem and after 1/2 hour on it, still dont have right answer.

The answer supposedly unlocks an excel sheet and by signing my name it states "solved it"

well at last count my answer was 9708 but not the right answer

so here below is the promblem...can anyone help!

This is a 5th grade math problem. If you can open the spreadsheet, you'll see it's a very small list of people who have got the correct number. This is not a trick question. This is a real maths problem so don't say that a bus has no legs. The bus driver is not part of the equation.

• 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 on 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.
Good Luck!
