Step-by-step explanation:
Arrange 6 girls first in 6! ways.
Then we have 7 spaces to arrange 5 boys.
Therefore total number of ways to arrange boys = Number of ways of selected 5 of the 7 spaces * Number of ways to arrange those 5 boys in those 5 chosen spots = (7c5)*5!
Therefore total number of ways would be: (7c5)*5!*6! = 1814400
