Lake Kickapoo, TX, is approximately 12 km in length by 2.5 km in width.
The inflow for the month of April is 3.26 cubic meter per second, and the outflow is 2.93 cubic meter per second. The total
monthly precipitation is 15.2 cm and the evaporation is 10.2 cm. The seepage is
estimated to be 2.5 cm. Estimate the change is storage during the month of April.

Convert evaporation, rainfall and seepage to cubic meters by multiplying the appropriate level changes (in meters) by the lake area (in square meters)
Then use
Storage level change =
(Inflow)  (outflow) + (precipation)  (seepage) (evaporation) 
Thanks, I wasn't converting to cubic meters. Now I got it!!!!!!
