: The answer is 1064.96 pounds...but how? Thanks anyway
Irene,
I have good news and bad news.
The good news:
I made a terrible blunder in my work.
I used y for the depth.
It should have been 4-y.
So the integral is:
125 INT(4 - y)y^(1/2) dy [from 0 to 4].
The bad news:
I went through my corrected version and came out with *another* wrong answer: 1066.67
I'm much closer! (Do I get partial credit?)
Seriously, now I can't find any errors in my work.
I hope someone can straighten me out ~ gently, please.
