How many bricks does it need to be 24 meters long and 3 meters wide? The length of the brick is 40 cm and the width is 20. How to calculate how many bricks


24*3=72
0.2*0.4=0.08
72÷0.08=900



I want to build a steel structure house with an area of about 210 square meters, three stories, 17.5 meters in length and 12 meters in width. How much is the total cost?


In Changchun City, Jilin Province, the price is between 200000 and 300000, the key is the complexity



The length is 9.8, the width is 12.9, and the area is 240 square meters. How much is the cost of two ordinary buildings?


If it is brick concrete structure, about 800 ~ 1000 yuan per square meter, we have this price (Yangzhou)



How do they calculate the width and length of the house


Square meters! It's length times width! The house has building area and usable area! The total area of each floor of the building is calculated according to the section above the corner of the building, including usable area, auxiliary area and structural area



My house has a width of 6 meters and a length of 8 meters. How to calculate the square meters? Is length multiplied by width equal to square meters? How to calculate the area


The building area also has to add the wall area and the shared area



As shown in the figure on the right, a 50 meter fence against the wall is a rectangular fence. What is the area of the fence? The height of the rectangular fence is 10 meters


Fence length = 50-10 × 2 = 30m
Area = 30 × 10 = 300 square meters



A 24 meter long railing is used to form a rectangle against the wall. How many square meters is the largest area of this rectangle


There are two ways of leaning against the wall. When the length and width are in whole centimeters, the following results are obtained. The first one is to choose the long side leaning against the wall. (1) when the width is 1, the length is 24-1 × 2 = 22, the area is 1 × 22 = 22 (square meters) (2) when the width is 2, the length is 24-2 × 2 = 20, the area is 2 × 20 = 42 (square meters) (3) when the width is 2



As shown in the figure, how to use a wall (the length of the wall is unlimited) and a 20 m long fence to form a rectangular field with an area of 50 M2?





A rectangular fence is twice as long as it is wide and covers an area of 130 square meters. What is its width


Radical 65



Mathematics: the surface area of a cuboid is 67.92 square decimeters, the bottom area is 19 square decimeters, the perimeter of the bottom area is 17.3 decimeters. What is the volume of a rectangle


Let length, width, and height be a, B, and C respectively, then AB = 19,2 (a + b) = 17.3,2 (AB + AC + BC) = 67.92
The results show that C = 29.92 / 17.3, volume = ABC = 19 × 29.92 / 17.3 = 32.86012 decimeters & sup3;
