1.3962634 cubic feet Nominal
A 16-inch diameter tube that is 200 feet long has a volume of: 279 cubic feet.
To find the volume of a tube, you can use the formula for the volume of a cylinder: ( V = \pi r^2 h ). For a tube with an 18-inch diameter, the radius is 9 inches (or 0.75 feet). The height is 40 feet. Plugging in the values: ( V = \pi (0.75)^2 (40) \approx 70.69 ) cubic feet.
1 cubic foot of aluminum weighs 169.344 Lbs
0.0833
The formula is pi X radius squared X length. (Assuming the tube is round!) Thus, 2 X 2= 4 X 3.14159 = 12.566 X 240 (Length in inches) = 3015.84 Cubic inches = 1.74528 cubic feet.

4 inch diameter hole assumed Take 4 inches as 1/3 foot > volume = pi * r * r * l = 3.1416 *1/6 * 1/6 * 28 = 2.443 cu. feet
Assuming that your tube has an INSIDE diameter of 3 inches, then the volume will be that of a cylinder. V = (pi)r2h = 3.14159x(1.5)2x36 = 254.46879 cubic inches 231 cubic inches = 1 gallon, so divide, 254.46879 / 231 = 1.10159649 round to 1.1 gallons
We need to know the dimensions of the tube. The diameter AND the length of the tube. It takes o.465 yards per foot of length for a tube 4 feet in diameter. .
A cubic inch in a measure of volume - in 3-dimensional space. The only information provided is that for 2 dimensions - that is, an area. It is therefore impossible to give a sensible answer.
