You are tiling a room with 1 foot squares tiles.The room is 11 feet 8 in wide and 15 ft 8 in long. How many whole tiles will you need?How many tiles will need to be cut? Each box of tiles covers 10 square feet. How many boxes of tiles will you need?
Are there no windows or doors in this room ? No other obstructions which affect the wall area ? In any case, it is impossible to determine how many tiles you will have to cut. It depends on where you start tiling, as well as the bits that you have to work around, like doors and windows, and so on. But, crucially, it is also important to know the height of the room. Work out a rough area and add, say, 15% for the ones you have to cut. So, if the room is h feet high, you will need 2 x (12h + 16h) = 2 x 28h = 56h square feet. Add 15% and you get 65h square feet (that is, 6.5h boxes of tiles). (But you can subtract the area of any doors, windows, etc.)
Because the remainder on each side is more than half a foot (8 inches > 6 inches), you will not be able to use the leftovers from cutting one tile to fill the spot for the next tile. We round both dimensions up to the next foot and get 12 feet by 16 feet. This tells us we need 192 total tiles. We will have to cut 16 tiles along one side, and 12 tiles along the other. One cut tile is shared between the two sides, so we're really only cutting 16 + 12 - 1 = 27 tiles. So: 192 - 27 = 165 whole tiles (which we can also see by rounding the dimensions down to 11 by 15 and multiplying). 27 cut tiles. It will take us 19.2 boxes to get 192 tiles, so we round up to 20 boxes.
I believe the answer for the first question is 192. You are ASSUMING that you need not to count the cut ones. The first part of the problem saids You are tiling a room therefore you need to supply with whole tiles, a store will not sell cut and you cannot cut what you have not purchased. For any engineer, architect, builder the order of process is total needed, and then how many need to be cut and then you place your order so you need to know the number of packages. If answered your way that is when you see people going back to the store to buy more because they did not think orderly.
