75 Square Feet of Tile should do you the trick, but that's including approx 15% waste. You Can Always Return Unused tile to your Supplier, remember they sell by the square foot. Or Linear in some cases, so you can return any untouched tiles/mosaic strips (no cuts, no breaks, no sealed and no tiles set with mortar and then pulled up etc.) Just Remember to buy enough Mortar/Grout to cover 75 square feet each. Have Fun.
