How many bags of 25 liter top soil would you need for a tonne?

To determine how many 25-liter bags of topsoil are needed for a tonne, we first need to know the density of the topsoil, which typically averages around 1,200 kg/m³. Since 1 tonne is equivalent to 1,000 kg, this means you would require approximately 0.83 cubic meters of topsoil. A 25-liter bag is equivalent to 0.025 cubic meters, so you would need about 33 bags (0.83 ÷ 0.025 ≈ 33.2).
