Neco 2019 Agricultural Science Question 5
Practice objective / multiple choice question 5 from the 2019 Neco Agricultural Science examination.
A teak stand of \(800\) trees has an average diameter at breast height (DBH) of \(30\) cm at age \(20\) years and an average height of \(12\) m. DBH increases at \(0.8\) cm per year and height increases linearly at \(0.6\) m per year. Tree volume (m³) is given by \( V = 0.0005 \times D^{2} \times H \) where \(D\) is DBH in cm and \(H\) is height in metres. After \(10\) years a selective harvest removes \(15\%\) of the trees. Calculate the total timber volume (in cubic metres) that will be available from the remaining stand after the \(10\)-year period.
