Xiaoming's house covers an area of 1.20 square meters, with 300 square bricks on the ground and a side length of 0.6 meters. There are three situations:
All the floors are paved with square bricks, and 120 is greater than 108. Obviously, 300 bricks is not enough. It is also unreasonable. In general humid areas (such as bathrooms, kitchens and balconies), quick drainage should be considered. Tiles should be laid with slopes, and small-sized tiles are easier to slope.
Using the second part of the area (except the bathroom and kitchen), the paving area includes the bedroom, living room, hall, aisle and storage room, so that the square brick area with a welt length of 0.6 meters is less than 108 square meter, and then 300 bricks are enough.
San Xiaoming's family thinks that the floor is better, so 300 square bricks with a side length of 0.6 meters are useless, or only occupy a small area for paving, and 300 bricks are more than enough.
It is best to confirm the scheme first, and then choose the materials. Now the ground can be paved with bricks, floors and specially customized construction treatment; Even if it is paving bricks, there are many choices, and the combination of paving methods.
Sales area: Commercial houses are sold as "suites" or "units", and the sales area of commercial houses is the sum of the interior or interior construction area (hereinafter referred to as interior construction area) purchased by the purchaser and the public construction area to be shared. Sales area of commercial housing = interior construction area+shared public construction area.
Interior usable area: refers to the usable area of the house in the suite, which is calculated by the horizontal projection area according to the following provisions: 1) The sum of the space areas of the bedroom, living room, hallway, kitchen, bathroom, bathroom, storage room and closet in the suite; 2) The stairs in the suite are included in the usable area according to the total area of natural floors; 3) Chimneys, ventilation pipes and tube wells not included in the structural area are included in the usable area; 4) Interior wall decoration thickness is included in the usable area. The usable area refers to the sum of the net area directly used for production or living in each floor of the building. The usable area is equal to the building area minus the structural area and ancillary area. Calculating the usable floor area of a house can directly reflect the usage of the house, but it is generally not necessary to use the usable floor area to calculate the price in the sale of the house. The usable floor area of the house is calculated according to the horizontal projection line of the interior wall of the house.
