The volume of the pool is given by:
[tex]V=w\times l\times h[/tex]Where "w" is the width, "l" is the longitude, and "h" is the depth.
Solving for "h":
[tex]\frac{V}{wl}=h[/tex]replacing the known values:
[tex]\frac{3000m^3}{(50m)(25m)}=h[/tex]Solving the operations:
[tex]\frac{3000m^3}{1250m^2}=h[/tex][tex]2.4m=h[/tex]Therefore, the depth of the pool is 2.4 meters.
