When I saw your thread title, I automatically thought, "He's put the dimensions into the BIABacus and found his pot actually holds more than 80 litres!"
Some pots marketed as
x amount of litres often hold more than advertised, as they are, in catering, often selling the volume that can be reasonably cooked in the pot - eg the volume based on handle height.
But.... Brendan they have definitely delivered you the wrong item or they are ripping you off.
Formula for the volume of a cylinder is V = pi x radius x radius x height.
i.e. 3.14 x 22 x 22 x 40 = 60.8 L
This can be checked
here.
Let us know if they just made an innocent error Brendan or whether we should avoid them. Hope all turns out well.
