Convert the back splash dimensions to inches. Calculate the areas of the back splash and a tile. Then divide the total area of the back splash by the tile area to get the number of tiles required, which is 192 tiles.
To determine the number of tiles needed, we first need to convert the dimensions of the back splash from feet to inches since the size of the tiles is given in inches. So, the back splash is 2.5 feet tall equal to 30 inches (because 1 foot = 12 inches and 2.5x12 = 30) and it is 8 feet long which is 96 inches (because 1 foot = 12 inches and 8x12 = 96).
Next, we calculate the area of the back splash by multiplying the length by the height which is 2880 square inches (30 inches x 96 inches = 2880).
Then, we find the area of a tile by multiplying the length and the width of the tile: 2.5 inch x 6 inch which equals 15 square inches.
Finally, we divide the total area of the back splash by the tile area to get the number of tiles required. So, 2880 square inches / 15 square inches equals 192 tiles.
