Neco Model Questions Vol1 2024 Agricultural Science Question 27
Practice objective / multiple choice question 27 from the 2024 Neco Model Questions Vol1 Agricultural Science examination.
The timber volume (in m³ per hectare) of a fast‑growing species after \(t\) years of growth is modelled by \(V(t)=0.08t^{3}-0.9t^{2}+30t\) for \(5\le t\le25\). The stand is harvested at a rotation age \(R\) and immediately replanted. Determine the integer rotation age (in years) that maximises the average annual timber yield \(\frac{V(R)}{R}\).
