I did; fuck 27 and 28 were hardJosephW said:How did everyone find short answer? I didnt find any of them that hard.
Was the cheese question, you had to use cosine rule to get how wide the box is?

No cause that will give a greater length. U had to use cosine to get a straight length.samjohnno91 said:wasnt the cheese question arc length formula, and then you times your answer by four to get the amount going across?
Not really. The arc length will be longer than required because it includes the curve. You needed to use cosine to actually work out how wide it was.samjohnno91 said:wasnt the cheese question arc length formula, and then you times your answer by four to get the amount going across?
i put a line down he middle of the triangle to spilt it up into 2 right angle trianges, then used sin20 = x/15 , n doubled that answer.JosephW said:No cause that will give a greater length. U had to use cosine to get a straight length.
I can either go around a football field to point A or go straight through it. Is it the same distance walked?samjohnno91 said:im a bit confused, looking at the diagram, it shows the cheese with the curve at the bottom being taken into account and that each ends of the cheeses touch the side of the box. All cheese blocks at their respective ends just touch, so still dont see why arc length wouldnt work.
and then to find the 3 going across i just did 7x3
