A box is a cuboid with dimesions 26cm by 15cm by 20cm all measured to the nearest centimetre. disc cases are cuboids which measure 1.6cm by 14.2cm by 19.3cm all measured to the nearest millimetre.

If the disc cases are stacked as shown, show that it may NOT be possible for 16 cases to fit in the box.

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
