APPRENTICE HELP

[PRACTICEKINDNESS]

Hi Guys,

I’m an apprentice who is really struggling with practicing a materials quantity section of my upcoming exam.

Can anybody please and help me with this:

I have a triangle shaped stud wall,

2240 x 2507 which is 5.6 squared metres

I have cladding with is

100mm height and 1.8metres long.


How much cladding do I need to cover the area of the stud wall.

Does anyone have any methods or maths calculations

Assuming the base is 2507 and the height is 2240 you divide the height by 100 to get the number of verticle stacked lengths, in this case 22.5. The longest length would be the first plank which would be made up of two pieces 1.8 plus one at 707. The following courses would be less the cut out for the side angle of the one below. This would normally be done on the job to ensure a fit rather than maths. In this way, you work along making the best economical cuts of your planks as the span becomes continuously smaller. This is done by eye as you can plainly see what offcuts can be used to minimise waste. That is how I would do it but each to their own way, the most important thing is speed of work, minimal waste, and a tight fit.

2240 x 2507 which is 5.6 squared metres

thats if its square , not if its a triangle
are they simply trying to see if you can work out the area of a triangle
need to divide by 2

just a DIYer

this is not for a test , so likely wont help here

but just how i would go about it
i would draw a square 3.6 (2 off 1.8s)
by the height
and then divide the height up into the 100mm lines
the draw a vertical at 1.8m (allowing maybe for finish/squareing edge
and then draw the triangle and work out the full 1.8m needed and the cuts and how many of the waste cuts i could use from the top down.
takjing into account if the squaring of waste or if the cladding can be turned over for the angle cut to lineup

but i do the same for tiles on a wall /floor - rather than just work out the area needed, and the cuts , still add about 10% for mistakes - depending on how buying if by box or individually , as my time is not on a job and needing to be paid for -

so may not help

I just looked at this again and it is more a case of how many lengths are needed to cover the area. You make no menton of the exposed face of the board as the joint will reduce the face to less than 100mm and therefore you would have to use the exposed face for the calculation. The short board lengths of 1.8 will require more than one plus one board cut for the lower but as you get to the upper part of the triangle one board could cover a number of spans. My gut tells me 15 lengths. In the real world a cladding guy would make a rough guess on experience.
