Area of each of the tiles = (2.5 * 6) inches^2 = 15 inches^2 Now we have to get down to the case of the backsplash 1 feet = 12 inches Then Length of the back splash = 8 feet = (8 * 12) inches = 96 inches Height of the back splash = 2.5 feet = (2.5 * 12) inches = 30 inches Then Area of the back splash = ( 30 * 96) inches^2 = 2880 inches^2 So The number of tiles required to fit in the back splash = 2880/15 = 192 So 192 tiles will be required to fit in the back splash. I hope the procedure is clear enough for you to understand.
