The following is the first in a series of attempts at solving the world's problems using math that I'm developing on my whiteboard. Enjoy!
The Bedsheet Sufficiency Formula
Formula
B = 1.25[(lw) + Σ(πr2h)n]
Variables
B is the size of the blanket or sheet required to cover all people in the bed.
lw is the standard area formula for a quadrangle, in this case, the sheet.
πr2h is the formula for the area of a cylinder, in this case, a crude approximation of a person.
n is the fact that this formula works for any number of persons in the bed, to be added in sum.
Basis
I am often victimized by the nefarious sheet-stealers who have ruined countless nights of my sleep. In an attempt to remedy frigid nights in the future, I have developed this formula to ensure the warmth of generations of sleepers to come. Huzzah!
