Thank youuu! =) I understand now. When I solve the entire problem I get out: 7.813e10 =)

Thank you very much for your help! =) I'm assuming all of you tried giving me different ways to solve this problem??

thank you. i tried doing your suggestion, so I got: 1000 * 9.8 * 75 = 7.35 x 10^5 as pressure Then I added it on to 101,300 N/m^3 (atmospheric pressure) and I did F=PxA like you said... which gave me 1.778 x 10^11 but according to Haths... it should be 7.8 x 10^10 What am I doing wrong? =/

So I used the formula: n(n+1)/2 ; where n is the height of the dam. When I sum up all the numbers on the right bracket I get a total of 2850. And I multiplied that by 1000*9.8 and I get 2.793 x 10^7... & I found F=PxA but it doesn't workkkk because I still get the same answer from the beginning...
