AQA GCSE Mathematics Paper 3 (Higher) 8300/3H - 14th June 2023 [ Exam Chat]

If anyone can explain to me step by step how you got your answer for the maximum and minimum cube question if you think you got the right answer? I was confused as hell

Yeah same but i got like 792 or sm and then the minimum i gave up on

I got 792 for the maximum and 165 for the minimum.
For the maximum you can draw a sketch of the shape by connecting the rectangle you get for the front elevation to the weird shape you get for the side elevation and then filling in the shape to make a 3d shape. Then you can work out the volume of the shape you get and that will be the number of centimetre length cubes you need. This should give you 792.
For the minimum you can draw a sketch of the shape by again connecting the rectangle and the weird shape you get for the side elevation. However, this time you should increase the depth of the shape you get by 1 cm so its not completely filled in like you did for the minimum. The calculation for this one is the (area of the weird shape)+(area of the rectangle)-(area of the area where the rectangle and the weird shape connect). So you should get (66)+(108)-(9)=165.
I've tried to explain it as well as I could and I hope it makes sense but if anyone has any questions feel free to ask! I'll try my best to answer them.

surely they will be lower this year, last years papers were a joke

For do the brothers get more than £430 I put yes, they all got like £437.50. Did anyone else get that?

Also for the trig question was it tan rule I can't remember what answer I got

hi guys for the ratio question i got k=1.5 but it should have been 6. i did all the correct working, just with the wrong values, so i ended up getting 3:20 but it should have been 3:5. it was 4 marks, how many do u think i would get? because its error carries forward for the whole thing basically

I GOT 3:20 TOO, but idk if its wrong. How many marks would i get

no problem! dont worry, u will get 2 put of 3! and im sure about that. with transformation questions like this theyre always 3 marks.
1 mark for saying enlargement
1 mark for saying the scale factor
1 mark for centre of enlargement
im very sure u will get 2 out of 3!

thats so weird how did we both make the same mistake. i asked my teacher he said 2 or 3 /4 for error carried forward

What did everyone get for the last one? (The bearings)

234

btw i got 234 and a decimal next to it but it rounds to 234, i never rounded it and kept it in a decimal. Am i wrong?

nope, youre actually correct, bearings shouldnt be with decimals. youll get full marks on that!

What did you guys get for the question where it asked whether the guy gets home by 2:30 pm or not?

instead of saying centre of enlargment i said: about the point(7,4) is that correct?

i put a decimal helppp
