    area of a circle x height

    = (pi * radius^2) x height

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

    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.

    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. 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.
