Question
In determining the volume of water impounded in a reservoir by the contour-area
method, a planimeter is used on a map of scale (1/2,400 ). areas in square inches on
the map between the lower contour line 1 and the higher contour line 4 were
determined in the table below
Contour interval on the map is: 9 ft.
Compute the reservoir water volume in the unit (Acre-foot).
Round your answer to 2 decimals.
