Answer

A - Flashing B - Timber Batten C - Wall Panel D - Floor Covering

Step 4

Describe the function of B.

Answer

The function of B, which is the timber batten, is to provide support for the wall panel and to enhance the aesthetic appeal by offering a finished look. It also serves as a fixing point for the paneling.

Step 5

What material is used for this specific part in C?

Answer

The material used for part C, which is the wall panel, is typically plywood or MDF (Medium Density Fiberboard) as these materials provide a smooth finish and are easy to work with.

Step 6

The area of roof tiles needed.

Answer

To calculate the area of roof tiles needed, first determine the total roof area. Assuming a standard pitch, the area can be calculated using the formula:

$Area = ext{Length} imes ext{Width}$

Considering the spacing and additional dimensions from the specifications, round the total area to one decimal place.

Step 7

The number of roof trusses needed.

96%

114 rated

Answer

The number of roof trusses can be calculated using the formula:

$ext{Number of trusses} = rac{ ext{Total roof length}}{ ext{Spacing between trusses}}$

Given the centre-to-centre spacing of 500 mm, convert the total roof length from mm to m and divide by the spacing.
