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
