    Im going through a past paper and I'm stumped on a question:

    "Six balls fit inside a box, the balls each have a diameter of 5cm, the box is a cuboid"
    "work out the volume of the box"

    I know how to find the volume of both a cuboid and a sphere however im struggling to understand how I go about solving the question. My initial reaction was to work out the combined volume of all six balls however I then realised that there must be spaces between the balls somewhere so it couldn't be correct.
    Any suggestions on how to go about solving the question?

    thanks!

    six balls can only be arrange one on top of the other so base will be area of base will be 25 and height will be 30 so 25*30=750cm^3 .
    that's the answer I think unless I'm missing out something.

    That looks right, thank you so much!

    I think the main trick is the cuboid many people would miss it out and try sorts of things and they forget that a cuboid has sides equal
