Waec Model Questions Vol1 2018 Agricultural Science Question 36
Practice objective / multiple choice question 36 from the 2018 Waec Model Questions Vol1 Agricultural Science examination.
A forest area of 10 ha is to be established for timber production. Each hectare is initially planted with the same number of saplings. The annual survival rate of the saplings is 90% (i.e., each year 10% die). After 10 years the volume (in cubic metres) of a surviving tree is given by V = 0.02 t², where t is the age in years. The farmer wishes to harvest exactly 1 200 m³ of timber at the end of the 10‑year period. How many saplings must be planted per hectare (rounded up to the nearest whole sapling) to meet this target?
