Answer:
length of beam = 9 m = 900 cm
breadth of beam = 50 cm
height of beam = 20 cm
volume of beam = L × B × H
= 900 × 50 × 20
= 9,00,000 cm³
= 0.9 m³
weight of wood per m³ = 30 kg
weight of beam = 30 × 0.9 = 27 kg

Answer:
L = 9 m
B = 0.50 m
H = 0.20 m
volume = L*B*H
= 9*0.5*0.2
= 0.9 m cube
weight of rod = 0.9 * 30 = 27 kgs
