A cuboid tank is 10 meters long, 4 meters wide and 2 meters deep. How many liters of water can it hold at most? How many square meters does it cover?

A cuboid tank is 10 meters long, 4 meters wide and 2 meters deep. How many liters of water can it hold at most? How many square meters does it cover?


Volume v = 10x4x2 = 80m & # 179;
80m³=80000L
Floor area s = 10x4 = 40 M2



A cuboid pool is 50 meters long, 20 meters wide and 2.5 meters deep. How many square meters does it cover?


50 × 20 = 1000 square meters of floor area



Normative speaking, the unit of land occupation is mu or square meter, so what about the construction area?


Generally, the domestic area of one mu is 666.66 square meters, and the building surface is directly calculated by square meters. Because one mu is too large, the building area of 120 square meters is not small, so it can't be calculated by 0.2 mu
The area of a small site is also calculated in square meters



What are floor area and building area respectively?


Building area, also known as expanded building area, refers to the sum of the plane area of each floor measured by the exterior wall peripheral line of a residential building. It is an economic indicator of the scale of a building, It refers to the use area, auxiliary area and structural area. The occupied area refers to the area index on the land use certificate obtained by the project. The area of the above ground part in the building area △ occupied area = the plot ratio of the land



What's the difference between floor area and floor area?
A two-story building covers an area of 1500 square meters and a construction area of 5000 square meters,
How did it work out?
Is the roof (hard top) also a building area?
I've seen the rules of building area calculation, but I still can't
1500 * 3 = 4500 is the fence also included?

6. For buildings on slope land, if the hanging feet are used as overhead floor and the floor height is more than 2.2M, the building area shall be calculated according to the horizontal area around the enclosure
7. The building area of the passageway through the building, the hall and the hall in the building, regardless of their height, is calculated as one floor. The building area of the corridor in the hall and the hall is calculated as its horizontal projection area
8. The building area of the library's stack room is calculated according to the bookshelf
9. The building area of elevator shaft, lifting shaft, garbage channel and pipe shaft is calculated according to the natural floor of the building
10. The building area of stage lighting control room is calculated by multiplying the horizontal area of surrounding structure by the actual number of floors
If the height of the technical floor in the building exceeds 2.2M, the building area shall be calculated
11. The building area of awning with column is calculated according to the horizontal area of column, and the building area of awning with independent column is calculated according to half of the horizontal projected area of top cover
12. The construction area of car shed and goods shed platform with column is calculated according to the horizontal area of column periphery; the construction area of car shed, goods shed and platform with single row column and independent column is calculated according to half of the horizontal projection area of top cover
13. The building area of staircase, water tank room and elevator room with enclosure structure protruding from the roof shall be calculated according to the horizontal area of enclosure structure periphery
14. For the door bucket protruding from the wall, the building area shall be calculated according to the horizontal area of the surrounding structure
15. The building area of closed balcony and cantilevered corridor is calculated according to their horizontal projection area. The building area of concave balcony and cantilevered balcony is calculated according to half of their horizontal projection area
16. The building area of the corridor and eaves corridor with top cover and column outside the building wall is calculated according to the horizontal area of the outer line of the column. 17. The building area of the corridor and eaves corridor without column is calculated according to half of its projected area
18. The construction area of the overhead corridor with top cover between two buildings is calculated according to the projected area of the corridor. The construction area of the overhead corridor without top cover is calculated according to half of its projected area
19. The building area of outdoor stairs used as main passageways and for evacuation is calculated according to the horizontal projection area of each floor; the building area of outdoor stairs with stairs in the building is calculated according to half of its horizontal projection area
20. The building area of a single storey elevated building crossing other buildings and structures shall be calculated according to its horizontal projected area, and that of a multi-storey building shall be calculated according to multi-storey
Do not calculate the scope of building area

How to calculate building area and floor area?
For example, a 9-story building, 72 meters long and 16 meters wide, what is its building area and floor area?


The floor area is the building area of the ground floor, if the rule is s = 72 * 16. The building area refers to the sum of the building areas of each floor, s = 72 * 16 * 9



What is the difference between building area and floor area?


The difference is very big
Building area, also known as expanded building area, refers to the sum of the plane area of each floor measured by the exterior wall peripheral line of a residential building. It is an economic indicator of the building scale of a building. It includes three items, namely, usable area, auxiliary area and structural area
The land area refers to the area index on the land use certificate obtained by the project
The area of the above ground part in the building area △ the floor area = the plot ratio of the land
