How do you calculate this problem?
Using the project documents, calculate the quantity of plasterboard (in m'2) for the double-walled installation wall between rooms 4.7 and 4.8 in the attic.
h = clear shell height
1)23.98 m²
2)32.31 m²
3)45.69 m²
4)47.95 m²
5)64.61 m²
The dimension of the wall is 3.77m. This time the wall height and then 4 because of the double-planking on both sides.
You wouldn’t do that. The wall would be thinly walled and then a stand system (example Geberit GIS stand system) would be installed in the bathroom (room 4.8) and simply planned. The system can better accommodate the sanitary items and there is no reason for planning in the storage room (room 4.7). The jobs would be lower and you would save money. By means of the stand system and the walling, one would have a deposit in the bathroom, which is advantageous and would not have to plan high space.
By calculating both the surface of the wall from the side of the bath with the height still standing somewhere, as well as from the side of the storage room (which may be equal to that) and this area is then double-planned x2.
But then why a lot of gypsum boards in m’ (?) are asked, but the solution options are offered in qm, you should check again.
