Volume and length expansion with beta and alpha

[kgm01]

Summary: Help with volume and length expansion question

Hi, I am struggling with this question. I understand that beta = 3 alpha so you use this to sub into the volume expansion equation. Is this correct? Can someone please provide a step by step instruction on how to do this question? Thank you !

Hello kgm, $\qquad$ $\qquad$ !

Not he way PF works -- see guidelines -- you have to post a real attempt

But an obvious first step is:
Write down the volume expansion equation for the oil and for the pot

Hi, sorry about that. I have reposted the question (hopefully in the correct format) in a separate thread. Thanks!
