# 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.
