    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 in the bus?

    2(7) + 7(7)(4) + 49(7)(4)
    14 + 196 + 1372 = 1582
    But to be technical, there are 14 legs and 1568 paws.

    To explain it I would like to make a chart

    Girls 1 2 3 4 5 6 7

    B.Pack 7 7 7 7 7 7 7

    Big cats 7x7 7x7 7x7 7x7 7x7 7x7 7x7

    Total Big cats for seven girls= (7x7)x7=343 ---------A
    Each big cat has 7 small cats so total small cats=343x7=2401----------B
    Total cats =A+B=343+2401=2744
    Total legs for cats = 2744x4=10976
    Total legs for girls=7x2=14
    Therefore total legs for girls and cats=10976+14=10990 (except bus driver)
    I think giani513 answer is correct
