QUESTION 1:

Find the amount and price of boards:

Key:

Wall Height = 2400

Window Height 1+2 = 1300

Window Height 3 = 1200

Window Height 4 =1500

Door Height =2100

The Cover of the boards is 160mm.

The Total waste of 7%

Boards at $7.25 per meter

Perimeter:

The total perimeter of the sight in question is five thousand and two hundred (5200mm) multiplied by two and eight thousand five hundred and fifty (8550mm) also multiplied by two equally 10400 and 17100, these are the added together to equal 27’500mm or 27.5m.

Net Area:

The net area of all the walls on site then equals the above perimeter times the height, of 2400, this equals sixty six square meters. (66 sqm)

Area of openings:

Once the net area of wall space is found you need to add up all the openings and then subtract them for the gross area of cladding.

Window one and two

Are both 1300 high and sixteen hundred wide, this means they both equal 2080 or 2.08sqm; for a combined total of (4.16 sqm.)

Window Three

Is 1200 high by 1100 wide, equalling an area of (1.32sqm).

Window Four

Is 1500 tall by 1700 wide, equalling a area of (2.55 sqm)

Door One

The door is 2100 by 900 high. Equalling a total area of (1.89 sqm)

Total Openings:

= 9.92sqm.

Gross Area:

Is the Net Area take the total area of all openings on the façade of the building, this means the equation is 66sqm subtracting 9.92 sqm, equalling (56.04 sqm).

Lineal Meters:

The total length of board is simply the gross sqm of boards divided by the covering height. So the equation is then 56.040 divided by 0.160, this equals three hundred and fifty point, zero two five. (350.025 Lm)

Total Waste:

Carpenters should ensure they have sufficient waste to ensure they have enough meter age through the job. I did the sum as follows 350.025 x 0.7 = answer x 0.1, moving the decimal place over one, this equals 24.517m onto of the original 350.025 equalling a total length including waste of 374.542m

Cost:

The price is done per Lm so we times the number of meters by the price per meter, this being $7.25, equalling $2715.433

QESTION 2:

Find the total area and cost of cement sheeting:

Key:

Window 1 1500 x1500 = 2.25sqm

Window 2 1800 x1200 = 2.16sqm

Window 3 1800 x1800 = 3.24sqm

Window 4 1800 x1200 = 2.16sqm

Window 5 1500 x1500 = 2.25sqm

Window 6 1200 x1800 = 2.16sqm

Door 1 2100 x 900 = 1.89sqm

Sheet size: 2.7x 1.2m = 3.24 sqm

Waste: 7.5%

Cost per sqm is $6.45

Perimeter:

Is all the sides added together:

10,110 + 3,350 + 6,760 + 1,880 + 7,030 +5,150 = (34,270 or 34.27 m.)

Net Area:

Is the perimeter time the height,

34.27m x 2.4 = (82.24 sqm)

Area of Openings:

See Key for individual sizes. Total equals 16.11sqm

Gross Area:

Net Area subtract the openings, 82.24 – 16.11 = (66.13sqm)

Number of Boards:

Divide the Gross area by the size of the sheet, 66.13 divided by 3.24 = 20.41 sheet

Waste:

Additional waste is required for cuts, equalling 7.25. This would take the total sum to 22.889 sheets. Taking the total sheets when costing to 23 sheets.

If however you where to stand them vertically you could order 28 sheets and cut of 300mm equal to 11.11% of waste.

Cost

Is for 22 sheets, these 23 sheets equal 74.52sqm, the sheets are $6.45 per sqm.

So times the total sheet area by the price, equalling ($480.65)
