Given the rationale, provide a reasonable question and answer. Step-by-step reasoning process: There are 8 tiles along the width and 20 tiles along the height for a total of 8 * 20 = 160 tiles. Each wall has 160 tiles and there are 3 walls so there are 160 * 3 = 480 tiles in the shower.
 The question and answer:
Each wall of a 3 sided shower has 8 tiles running the width of the wall and 20 tiles running the height of the wall. How many tiles are in the shower?
The answer is 480
