This depends on whether you are doing your maths homework or actually going to do the tiling. In essence you must find the area of the floor (or wall) you intend to tile; then find the area of a single tile. The number-of-tiles is the area-of-the-floor divided by the area-of-a-tile. If this is your homework, then it is likely that whoever set the question made sure that you would need an exact number of tiles. It's probably worth the risk! For a real life situation, be aware that hexagons may not cut in as versatile a way as rectangular tiles. Buy some extras and take the surplus back when you've finished. The spacing between tiles for grouting can be ignored. Here's a worked example:
In this case, the easiest way to find its area is to take the 3 measurements shown: A, B and C The area of the tile will then be: Use either centimeters (eg 12.3cm), millimeters (eg 123mm) or inches and tenths (eg 4.8 inches) to measure. For example, if A is 20.0cm, B is 16.0cm and C is 30.0cm, the tile area is
must use the same measurement system as for the tile.
So, in this example we used centimetres (cm).
The floor's area is 140 x 230, which is 32,200 square cms.
Be careful to write down the figure correctly - with the right number of zeroes at the end.
32,200 / 460.0 which is 70 tiles exactly.
Wasn't that lucky (OK, I cheated and made it come out to a nice number; in a real life situation expect it not to).
One way the tiles will fit on the floor is like this: but there are many other ways. The key is to plan ahead, to save you having to make too many awkward cuts. | ||||
