Her answer uses 62.4 as her density-weight.
: : 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.
