if I were given this assignment, I would use V = 30 and R = 3 in the given equation - simplify to f(h) = 0.

Then I would calculate f(0) and f(3) and start the iteration process.

Please share your work and tell us exactly where you are stuck?

se eu tivesse essa atribuição, usaria V = 30 e R = 3 na equação dada - simplifique para f (h) = 0.

Então, eu calcularia f (0) ef (3) e iniciaria o processo de iteração.

Por favor, compartilhe seu trabalho e diga-nos exatamente onde você está travado.

How do I go from there? And know the 3 iterations? How to determine the relative error?

So you found

f(h) =100h³ - 900h² + 2864

You need to estimate the "roots" of this equation - using Bisection method.

Please study:

Bisection method - Wikipedia

Please come back and tell us what you found.
