BECE Science 2026 Paper

Concept:Number of birds $= \dfrac{\text{total floor area}}{\text{floor space per bird}}$Explanation:Recommended space per layer is $0.6 \text{ m}^2$.Total area of the poultry house is $72 \text{ m}^2$.Using the formula:Number of layers = $\frac{\text{Total area}}{\text{Space per bird}}$.So, Number of layers = $\frac{72}{0.6}$.To divide easily, multiply the numerator and denominator by $10$:$\frac{72 \times 10}{0.6 \times 10} = \frac{720}{6}$.Now compute: $\frac{720}{6} = 120$.Therefore, the poultry house can hold $120$ layers.Answer:Option D (120)
