area of a circle x height

= (pi * radius^2) x height

= (pi * radius^2) x height

pi*r^2*h

:fyi:

If you cant do the math, fill it with packing peanuts then dump them into a square box and take your measurements.

OK, but how do you figure ou the Cf of the square box? :)

Um...... Um....... I know this give me a minute........ Um.........

Ya know you probably have a point, if he cant do the math after being given the **** equation hes probably not going to run out and buy packing peanuts. :laugh:

OK the first thing you need to know is that there's 12 inches in a foot.

Once you grasp that, there are 12^2 sq. in. = 144 sq. inches in a square foot

If you can understand that then you'll see that there are 12^3 cu. in. = 1728 cu. in. in a cubic foot.

Yes, but what it do?

Lol it's called Volume....

I suggest you go back to grade school buddy, learn basic math all over again.

I guess there is always a need for garbage men... no need to go back to school; you're already qualified for that position!

Y'all are mean. :laugh: Radius squared times pi times the height (IN INCHES) gives you the volume in cubic inches. Divide that by 1728 (one cubic foot) to get the volume in cubic feet.

Ummm forgetting pie??? lol, you can't even do it.................

It's REALLY REALLY simple, how can that honestly not make sense...

(Radius x Radius) 3.14= area. Area x length = volume!!!! volume / 1728 = feet cubed
