Edexxel maths paper 3F

I found a few of the questions tricky on the foundation paper and wondered how other people did and what they got for the following questions

1. The question on why is the side elevation wrong in the triangular prism… I thought it was right and couldn’t see how it could be incorrect. I had no clue on this.

2. The question on density of a tin, confused the shit out of me… couldn’t do it

3. Finding out how many minutes it takes to fill up a 100 by 30 pool … tried A= pi x R2 but got a big long number with a bunch of decimals…

4. Also finding an equation for how many times a person wins or looses a game. It said use x and y …. No clue .

Let me know what u guys got!
