No, no guobao...you are looking for "Ask homework questions".  This is akaQA and we do not do your homework for you.

30 inches or 2 1/2 ft every month

365 inches or 30 feet 5 inches a year 

HI  I WILL HELP YOU WORK THIS PROBLEM OUT

YOU FIRSTLY WORK OUT THE CUBIC  FT LOST PER NIGHT  THEN MULTIPLY THIS BY DAYS IN MONTH

SO SURFACE AREA OF POOL IS   30ft X 22ft = 660 sq ft  THE DEPTH LOST IS 1inch PER NIGHT THEREFORE  660 X 1/12  = 55cu ft 

THERE IS 6.42851 UK GALLONS IN 1 CU FT  OR 7.485051 US GALLONS IN CU FT

THEREFORE  IN UK  55 X 6.42851 =  353.568 GALLONS LOST PER NIGHT

I WILL LEAVE YOU THE REST TO WORK OUT BY SUBSTITUTING  THE US GALLONS  THEN MULTIPLYING THE NUMBER OF DAYS N THE MONTH  OR YEAR

HOPE THIS HAS HELPED YOU

IF NOT POST ANOTHER QUESTION

You might be too late in doing guobao's homework. It was a week ago and the teacher is already upset.
