Hi
I am wondering if anyone can help me please, I'm trying to create a formula and am very close to pulling my hair out!
A helium cylinder holds 1.81m3 and costs £69.00 I am trying to create formula that will tell me how much it will cost to fill a balloon with different m3 eg. 11" balloon 0.015m3, 35" balloon 0.042m3.
Any help on this would be very much appreciated
Thanks
