Calculate how much m3 of water fell on 1 hectare of the earth’s surface, if the thickness of the sediment layer is 10 mm

To calculate how many cubic meters of water fell on each hectare of the earth’s surface, it is necessary to use the formula for determining the volume V of a rectangular parallelepiped with a base area S. The volume of water is V = S ∙ h, where h is the thickness of the layer of precipitation. The condition of the task says that the thickness of the layer of precipitation is h = 10 mm = 0.01 m, and the surface area is S = 1 ha = 10,000 m². Substituting these values in the formula, we obtain: V = 10000 m² ∙ 0.01 m = 100 m³. For clarity, since 1 m³ of water weighs 1 ton, 100 tons of water falls on 1 ha.
Answer: 100 m³ of water fell out.
