Question

33. What is the mass of 1 ha of soil to 15 cm g/cm, soil bulk density 1.5 Mg/m) 10, 000 m2 SUi a. 1,500,000 kg b. 3,038,608 kg 2,250,000 kg d. 2,250,000,000 kg e. 4,500,000,000 kg C.

Answer 1

Answer:

The correct option is: 2,250,000 kg  

Explanation:

Given : Area A = 1 ha (Hectare) = 10,000 m²

Bulk density = 1.5 Mg/m³ = 1.5 × 1000 kg/m³ = 1500 kg/m³ (∵ 1 Mg=1000 kg)

Depth of soil = 15 cm = 0.15 m   (∵ 1 m = 100 cm)

Volume  can be calculated by:

Volume = area × Depth = 10,000 m² × 0.15 m = 1500 m³

As we know, density = mass/ volume

Therefore, Mass of soil  = Bulk density × volume = 1500 kg/m³ × 1500 m³ = 2,250,000 kg
