Mathematical formula for the perfect Christmas tree

For those who prefer something more traditional than the Treeasy, members of the University of Sheffield’s Maths society have devised a formula for the perfect Christmas tree in response to a challenge by U.K. department store Debenhams.
The formula, which was created by students Nicole Wrightman and Alex Craig, uses the height of a tree to calculate the ideal number of baubles, length of tinsel, length of lights and even the height of the star, fairy or angel sitting atop the tree required to give the tree that catalog-perfect look.
“The formulas took us about two hours to complete,” said Wrightman. “We hope the formulas will play a part in making Christmas that little bit easier for everyone.”The "treegonometric" formulas are as follows:
- Number of baubles = √17 / 20 x (tree height in cms)
- Length of tinsel (cms) = 13 x π / 8 x (tree height in cms)
- Length of lights (cms) = π x (tree height in cms)
- Height of star/fairy/angel (cms) = height of tree in cms /10
For those without a calculator at hand, an online calculator can be found via the source link.
