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
