Hi there,
I'm currently studying Algebra & Quadratics in my Year 10 class. I came across this question which I found incredibly difficult to understand. My teacher was kind enough to help me out with it but my teacher, parents and uncle all don't understand how they got their answers. Could somebody please help me? It'd be much appreciated.
Question:
Algebra & Quadratics, Part 1 of Chapter 3
Factorising Using Common Factors 3.2
Open-Ended
Q13.
A paving tile has the shape and dimensions shown (x x x x y). Find two sets of values for x and y so that the volume (in cm3) has numerically the same value as the surface area (in cm2). The values do not have to be integers.
I've been told by my teacher that the answers are x = 12, y = 3; x = 8, y = 4
If somebody could help me understand how they got that answer, it'd be awesome, it's been baffling my whole family and I for the past week. I tried asking people on Quora but I have since had no luck.
Thanks.
Kind Regards,
Josh.
