Anyone want to help me figure out where I am going sideways in my math homework?


Recommended Posts

I'm working on my end of class homework for the math program I'm in. I think I have most of this problem correct, but I know the final answer is wrong. Anyone (or your kids?) want to help me find my error(s) in question 3? 😁 I tried to go to office hours for homework group, but our teacher didn't show up.

Agree with Jenne for part c. In part e, convert cubic feet to cubic inches. Then divide by 231 to determine how many gallons that is. I have:

20250 ft^3 • 12^3 in^3/ft^3=34992000 in^3

34992000 in^3/231 in^3/gallon=151,480.5 gallons

^ indicates exponent

I think the water dimension is 50 ft rather than 70 feet.  The 70 feet dimension would include the concrete.  
At least that is my best guess.

That, plus I think your conversion from cu ft to gallons is wrong.  When converting from cu ft to cu in, you only multiplied by 12, instead of 12x12x12=1728 (you wrote 231 cu in/ 1 cu ft, actually, but used 12).
