Rectangular roof
Our house's roof is rectangular. When it rains, the water drains through the gutter. How much water flowed from our roof during a storm when we know that 12 liters of water fell on every 1 m2 of surface?
The roof width is 6m, the length is 9m, and the slope of the roof plane is 37°.
The roof width is 6m, the length is 9m, and the slope of the roof plane is 37°.
