Question
What is the weight of one centimeter of surface soil
over one hectare of land?Solution
One hectare is equivalent to 10,000 square meters (m² ). Multiplying this by the thickness of one centimeter (0.01 meters), we get a volume of 100 cubic meters (m^3 ). Multiplying the volume of 100 m^3 by the bulk density of 1.5 g/cm^3 (which is equivalent to 1.5 t/m^3), we find that the weight is 150 tonnes (t).
