I need help calculating US liquid gallons

[steamdrivre]

Hi all,
This one is gonna be pretty easy for most of you but I never did understand it waaaay back in school. Word problems always confused me.

Here goes;
I have a rectangular water tank that is 4 feet wide by 3 feet tall. It needs to hold 825 gallons of water soooo,
how long does the tank need to be???

Thanks, guys...

9.2 feet will be real close. Each cubic foot of tank will hold 7.48 gal of water. 9.2 feet = 110 inches.

Formula is:
width*height*length*7.48052=825 which works out to 9.19 feet.

OMG! I can't understand that! I said I stunk back in school with this stuff. Sheesh, thanks, though. :hehe:

Can someone else help, please?

I needed that formula, too. OK, thanks, WYO.
