I got that answer but don't know how you'd figure it out if you didn't assume the other side was also 25cm which it isn't.

It said AE was 25cm. It was 3d trig

Hi, can anyone remember the question numbers and topics of that paper? Trying to work out wether my A is still possible

25sin18 x 215 doing it this way works they gave us AE = 25 cm and then you get for the small side of 7.72.... But then to work out the bottom side you had to use trig and assumed it was 25cm so 625-(small side) = that side, then 215/23... gave you 9.0.... So it was 23 x 9 x 7.72 (Not exact answer) which gave you around 1600. Then find 1/3 which is 553.66 or rounded. The thing even though it's the right answer it's wrong because the prism did not meet in the mid point and AE is longer than the other hypothenuse.

all you do is 3d trig. This finds the height. There is no need to find the base of the triangle as you do not know the volume of the triangle. It is easier to find the volume of the cuboid and divide by 3

It’s 347 boxes if you take up the entire volume of the container which is not possible due to the shape and dimensions of the boxes they don’t fill out the container perfectly

they r boxes not liquids, so u cant have 1/3 of a box. so its 4 boxes x 4 bopxes x 20 boxes

Bro, 12.5 x 2.5 x 2.5 = 75^3, 0.6^3 = 0.216. 3000/75 = 40. 40 x 0.216 = 8.64 or 8.65 rounded to 2dp. You didn't even have to figure out how many fit in the box. You are wrong bruzzer.


Ur wrong u gimp

3000/(4x4x20) = 9.375

alr good. initially i did the volume method that everyone is talking about but I then reaslised that it wont work cause the boxes have set dimensions

And you really think that that is worth 3 or 4 marks?
