The answers are incorrect....
Hmm, why not u give me the final and I try if I can get the ans?
Part b: cost of paint is proportional to the surface area, not length. Use (A₁/A₂) = (L₁/L₂)²
Part c: mass is proportional to the volume, not length. Use (V₁/V₂) = (L₁/L₂)³
Part c: mass is proportional to the volume, not length. Use (V₁/V₂) = (L₁/L₂)³
Answer for part a is correct. Part b is $1,440,000. Part c is 2g
I just need help for part c. I found the answer for part b
