C) 1 ft. 3 inches

D) 1 ft. 4 inches

E) 2 ft. 5 inches

total water filled in 60 mins = 60*3 = 180 cubic feet
volume of the swimming pool = x*x*h
180 = 12*12 * h
h = 180/144 = 1.25 feet = 1 ft and 3 inches

Hence option C is correct

In 60 Minutes the total water filled in pool is 180 cubic feet.
Now the pool is square pool with 12 ft width, so the find the depth of water we need to divide the total water volume by area of base of pool (ps vol of cubic figure l*b*h) here l and b= 12
so h = 180(12*12) = 1 ft and 3 inches ( ps 12 inches =1 ft)

Ok I think I got lucky on this question- can someone give me some feedback because even though I got the right answer there was a serious lack of deliberation with my method, and it took a while- not to mention it may be flawed. So I knew, given the stimulus, that 3 by 60 is the volume of the pool. I then divided 180 by 12 and got fifteen- for some reason my intuition said that means 15 inches and 1 foot is 12 inches with a remainder of 3 inches; therefore, 1 foot 3 inches. I don't understand how to divide 180 by 144 quickly in my head.
