Which is heavier, traditional red brick or gypsum wallboard?

/A few small questions about asking architectural experts for help

Ask some questions to architectural experts:

1, using 10 cm light brick partition wall, including powder wall and cement, the weight per square meter is more accurate;

The wall load depends on the bulk density of the light brick selected by the landlord. Generally, aerated concrete is 600kg/m3, 10cm 60kg/m2, cement mortar has a bulk density of 200kg/m3, and 20mm thick single-layer plastering is 40kg/m2.

2, with light steel keel and double gypsum board partition, weight per square meter;

This lightweight wall is about 45 kg/m2.

3. Separate a single five-inch wall with traditional red bricks, including powder wall and cement, and the weight per square meter is relatively accurate;

Brick masonry: 1800 kg/m3, multiplied by the specific wall thickness, and plastering with cement mortar is the same as before.

4. The horizontal 24 hollow wall separated by traditional red bricks, including powder wall and cement, has relatively accurate weight per square meter;

Empty bucket bricks vary with different masonry methods.

5. In addition to the above materials, are there any partition materials with slightly higher cost performance? The requirements are light and the price is not too high. If so, please recommend some.

There are also 50 mm thick color steel polystyrene sandwich panels and 0.5 mm thick double-layer color steel plates used in clean workshops. Price 130 yuan/m2. The bulk density is 1 1 kg/m2. You can think about it.
