A small tectangular box has a width of 18cm and a volume of 720cm.
a.)determine the height and the length of the box.
b.) is there more than 1 answer? Explain.

  • Math7 -

    volume of box = lwh
    720 = 18lh
    lh = 40

    so any two numbers l and h which multiply to get 40 will work.
    There is an infinite number of such combinations
    e.g. 5x8, 1.25x32 , 1/3 x 120 , etc
