Hello everyone, I'm doing a Maths assignment and I need some help with the following question;
Q1) Tradsepeople often ignore small irregularities in floor shape when calculating floor area.
a) Give an example of when tradsepeople would ignore such irregularities.
b) Give a DETAILED REASON why tradespeople ignore such irregularities.
I understand it a little bit but can't get my head around it.. Any help appreciated! Glad to join the site it will come in handy when I get around to home woodworking =]
I hate Assignments

As you'd know MB, it's all about working out the square meterage of a building or floor space.
So why would someone not think it's worth the hassle or time of working it out ?
Hmm.... I might have to think about that one for awhile
But maybe you'll be quicker at it than me :0
and if you're still stuck in a few days pop another post.

Its to do with the amount of product needed, not the square meterage.
There is a catch though, which I will explain.
OK here goes.
2 tile sizes, 40cm2 and 10 cm2
Take 4 tiles, each 40cm x 40cm. = 80cms
Lay them in a Square pattern 2 x 2
Total = 4 tiles.
Now, put a 15 cm wide plate in the middle of them, exactly where the tiles all intersect. You will need to lay tiles around the plate. Obviously you will need to cut them.
How many tiles do you need to complete the job?
Now I want you to use 10mm x 10mm tiles.
Same sized area, namely 80cms by 80cms.
You will need 8 x 8 correct?
Because you are wasting less tile area as the tiles are smaller.
BUT, you might use 63 tiles, not 64 (8*8). So what is the difference then? 1 tile?
Floor products are not liquid (except concrete). So you cannot mix up the scraps of floor tiles to make a whole tile again.
You need the same coverage of tiles, and you will have waste. But unless you can take out a whole square metre, you need to ignore the plate, as you will need parts of a square metre to go around ithe plate.
I will probalbly look at this in the morning, and retype it wojne I can see that I have confused everyone inclusing myself.
Hope I have put you on the right track.
