Your task: Answer the question below. Then download and open the attached Excel spreadsheet. The number of legs is the password to unlock the Excel sheet. Add your name to the spreadsheet and send it on to see who else can unlock it.
Note: This is not a trick question. This is a real math problem so don't say that a bus has no legs. Also, there is no driver on the bus, so don't add any legs for a driver.
There are 7 girls in a bus
Question: How many legs are there in the bus?
