OK! hi everyone... am just an uncle here trying to help out my nephew... with one of his math homework and the problem went like this...

there's is X town which has an area of 20 mi and during the past week it had an inch of rain. and so the question was how much rain did X town had in cubic feet...

we got it this way:

20mi we converted it to ft. and we got 105,600ft. [squared]<------- What conversion factor did you use 1 mi = 5280 ft & 1 sq.mi = 27878400 sq.ft.


and 1in. of rain we converted it to feet and we got 0.0833ft

and knowing from the problem that we were looking for the volume so i know the equation was L x W x H, but since the area was already given so L x W = area, so what we did was just multiply the AREA x H, and so we got 8,796.48ft of rain...

But when he got to school the teacher said it was wrong and the teacher's answer was 50,000,000.00ft.... how he got it i dont know...

so am asking people in this forum to look @ the problem and let me know if we overlooked on something or if the teacher was wrong... please enlighten us...

thank you much!!!
