IOM 2018, Блиц, английски — Задача 9

OLYMPIAD OF METROPOLISES. Moscow, September 3 · 3 септември 2018 г.

Условие

Physics students, who like fiddling, took 12 identical resistors with a resistance $R_i = 100$ Ohm each and connected them in the shape of a cube. They were wondering what the equivalent resistance of such a network would be if measured between two adjacent nodes. Help them by giving a numerical answer accurate to the first decimal.

The answer should be given in the SI units unless otherwise stated. If the numerical result turns out to be an integer, it should be given as the answer. Otherwise round the result to the first decimal. $g = 10\ \mathrm{m/s^2}$.
