This is the classic Resistor Cube drawn in a flattened diagram for probing in Multisim. The resistor designations are:
Rtft = cube top face top edge resistor
Rtfr = cube top face right edge resistor
Rtfb = cube top face bottom edge resistor
Rtfl = cube top face left edge resistor
Rvtl = cube top left vertical edge resistor
Rvtr = cube top right vertical edge resistor
Rvbr = cube bottom right vertical edge resistor
Rvbl = cube bottom left vertical edge resistor
Rbft = cube bottom face top edge resistor
Rbfr = cube bottom face right edge resistor
Rbfb = cube bottom face bottom edge resistor
Rbfl = cube bottom face left edge resistor
The current probes show how current divides in branches relevant to a chosen path where KVL will be applied. Voltage probes are placed at the relevant nodes. KVL can be done through Rtfl, Rtfb and Rvbr or Rtft, Rtfr and Rvbr. The resistance of the cube is numerically equal to the reading at voltage probe PR12 and is equal to (5/6) Ω or 0.83333333333333333333333333333333 Ω.
