Waec Model Questions Vol1 2017 Agricultural Science Question 18
Practice objective / multiple choice question 18 from the 2017 Waec Model Questions Vol1 Agricultural Science examination.
A teak forest stand contains 120 trees per hectare. The average diameter at breast height (DBH) is 30 cm and the average height is 22 m. The form factor for this species is 0.55, where the volume of a single tree is V = form × π × (DBH/2)² × height. The forest manager wishes to harvest no more than 25 % of the standing volume in a year while retaining at least 80 trees per hectare after harvest. Determine (a) the maximum number of trees that can be harvested per hectare without breaching the minimum tree density, and (b) the total volume (in m³) that can be harvested per hectare under this constraint.
