Homework Statement
so my local supermarket is doing a competition were you guess the amount of ducks in this trolley . [/B]
Its summer here in Ireland I have no college so I am pretty bored and said i would have a go at solving this with maths , but because its summer time it also means I am having a lot of trouble getting my brain to work haha.

Homework Equations
area of a rectangle cube .
Archimedes' principle ( but i can't actually get my hands on a duck haha )
The Attempt at a Solution
So I was starting out by working out the size of the container the ducks are in ,
Im pretty sure the base of the trolley is 1 m^2 and the ducks look to go to around 1.5 m high .
this would mean the take up 1.5m^3 of space .
Next my educated guess would be each duck takes up about 200 - 300 mm^3 of volume but that is only a total guess .
now this is were it all went pear shaped .
I was imagining the ducks are cubes and working out what space they take up then i was going to factor in some error as they arent square and probably will be less ducks than the comparing square ducks .
but I am confused as to how to work this out . I tryed to convert 200mm^2 into m as the container is worked out in m ( 0.2^m3 ) and then divide it into the space ( 1.5 / 0.2 = 7.5 ) . so its pretty clear there is more than 7.5 ducks haha .
But my head is like mush and really can't work out where i have gone wrong .
