1. ## How do you figure out cubic feet in a circle box?

I am going to be using a circle box for a new setup, and I need to figure out how to get the volume. I know in a square box it is LxWxH/1728, but how do you do it in a circle type of situation??

that is correct

poor water in to find out how much water it can hold and then measure how much water you put in

(3.14 x R^2) x H

for instance if your cylindar is 18" across and 15" tall.....
R=9"
9x9=81
81x3.14=254.34
254.34x15=3815.1
3815.1/1728=2.21cu'

area of a circle is Pi x radius squared. so take the radius (1/2 the circle) and multiply it by it self, then times Pi (which is 3.14) Take all that and then multiply it the height to get the cubic inches. Divide by 1728 to get the cubic feet.

muy bueno.
