Abox has a length of 12 cm, a height of 22 cm, and a width of 18 cm. how tall would a stack of 12 of these boxes be? a. 144 cm b. 216 cm c. 264 cm d. 484 cm

Gas will most likely  fill the container 

The answer is 12, for the points

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
