Waec Model Questions Vol1 2025 Agricultural Science Question 14
Practice objective / multiple choice question 14 from the 2025 Waec Model Questions Vol1 Agricultural Science examination.
A forest covering 10 ha contains two species. Species A has an average DBH of 30 cm, height 20 m, wood density 0.55 t m⁻³ and 400 trees per ha. Species B has an average DBH of 45 cm, height 25 m, wood density 0.65 t m⁻³ and 250 trees per ha. Approximating each tree as a cone, its volume is V = (π/12) × DBH² × Height (DBH in metres).\n(a) Compute the total standing timber volume (in cubic metres) for the whole forest.\n(b) If a sustainable annual allowable cut is 2 % of the total volume, what is the maximum volume that may be harvested each year? Give your answer to the nearest whole cubic metre.
