How to calculate CBM of cylindrical object like a pipe or roll..?? An interesting question from a reader in response to my previous article https://www.shippingandfreightresource.com/2009/02/20/how-to-calculate-cbm-freight-ton/ on how to calculate CBM..
How do you calculate the volume of a Roll eg. a carpet @ 3.00m(length) x 0.60m (diameter)
Let me explain how to calculate CBM of a pipe or a cylindrical object..
Firstly you need to make sure that all measurements are in metres as usual.. Secondly we will consider a roll as a cylinder and the length of the roll is to be taken as the height..
The formula for calculation of volume of a cylinder = pi x r[squared] x h where
- pi is the ratio of the circumference to the diameter of a circle; approximately equal to 3.14159 (this is a standard measurement)
- r is the radius (half of the diameter)
- h is the height (equal to the length)
So in this case,
pi = 3.14159, r = .3 (half of the diameter) and h = 3
So using the formula pir[squared]h, the CBM = 3.14159 x .09 x 3 = 0.848 = less than a cubic metre
That will be end of the mathematics lesson.. 😮
