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?
There are 8 tiles along the width and 20 tiles along the height for a total of 8*20 = <<8*20=160>>160 tiles
Each wall has 160 tiles and there are 3 walls so there are 160*3 = <<160*3=480>>480 tiles in the shower
