Fiona completed 36 math questions in an hour. Shirley was able to complete twice as many math questions within that same time, and Kiana completed half of the sum of Fiona and Shirley's math questions. If they each did the same number of questions the following hour, how many math questions did all three girls complete in 2 hours? Let's think step by step and output the final answer after "####".

Shirley completed 36 x 2 = <<36*2=72>>72 questions
The sum of Fiona and Shirley's questions is 36 + 72 = <<36+72=108>>108
Kiana completed 108/2 = <<108/2=54>>54 questions
In one hour, they completed 108 +54 = <<108+54=162>>162 questions.
In two hours, they completed 162 x 2 = <<162*2=324>>324 questions.
