Carpet is laid on the surface of stairs with height of 3 and slope length of 5. It is known that the width of stairs is 2m, and the price of carpet is 5 yuan / m. how much does it cost to lay six identical stairs
Theoretically, it should be 7 meters long, but in real life, it should be put more, because the top and bottom should also be laid, assuming that the top and bottom add up to 3 meters, a total of 10 meters!
The specific formula is: X (2 power) + y (2 power) = Z (2 power), where x = 3 (high), z = 5 (slope), and y = 4 (ground length) is obtained from the equation
Then move the height of the six steps to the 3 meters high, and the length must be 3 meters. Similarly, move the length of the steps to the ground, "the length is 6 / 7 × 4 meters", because the first step is the first step on the ground, which can also be directly counted as 4 meters (after extension, it is actually 4 meters). No matter how many steps there are (the number of steps > = a finite number in real life), they are all the same length~
As shown in the figure, if carpet is laid on stairs with height of 2M and slope angle of 30 degrees, the length of carpet should be at least 2 meters___ m．
It is known that the height of a right triangle is 2m. According to the trigonometric function, if the horizontal right side is 2cos30 ° = 23, then the sum of the horizontal part of the carpet is the sum of the horizontal side, and the sum of the vertical part is the vertical side, then the length of the carpet is 2 + 23 M
After redecorating a hotel, it is considered to lay carpet on the main staircase in the hall. It is known that the width of the staircase is 3M, and its profile is shown in the figure. Please
Help calculate how many square meters of carpet you should buy
3 × (1.2 + 2.4) = 10.8 square meters
After redecorating, a hotel is going to lay some kind of red carpet on the main staircase of the hall. It is known that the price of this kind of carpet is 30 yuan per square meter, the width of the main staircase is 2 meters, and its side is as shown in the figure, so it is necessary to buy the carpet at least______ Yuan
As shown in the figure, use the translation line segment to move the stairs up and down to the right to form a rectangle, with the length and width of 5.6 meters and 2.4 meters respectively. The length of the carpet is 2.4 + 5.6 = 8 meters, and the area of the carpet is 8 × 2 = 16 square meters. Therefore, it costs at least 16 × 30 = 480 yuan to buy the carpet
After redecorating, a hotel is going to lay a kind of red carpet on the main staircase of the hall. It is known that the price of this kind of carpet is 40 yuan per square meter. The width of the main staircase is 2 meters, and the two true corners of the side triangle are 2.8 meters and 5.6 meters respectively. How much does it cost to buy the carpet at least?
``Calculate the area of the stairs' "upper area + front area" x the number of stairs + grow again X40 is at least how much money to pull```
After redecorating a hotel, a kind of red carpet is going to be laid on the main stairs of the hall. It is known that the price of this kind of carpet is 30 yuan per square meter, and the width of the main staircase is 2 meters
Figure: right triangle ABC, angle a = 30 degrees, BC = 2.8m
According to Pythagorean theorem, the length of the hypotenuse is 4.2 meters, the length of the other side is 3.5 meters, the length of the carpet is the sum of the lengths of the two right angle sides, 2.8 + 3.5 = 6.3, then the cost is 6.3 * 30 = 189 yuan
After the hotel is redecorated, a kind of red carpet is to be laid on the main staircase of the hall. It is known that the price of this kind of carpet is 40 yuan per square meter, and the width of the main staircase is 2 meters. The side of the carpet is shown in the picture. How much does it cost to buy the carpet?
As shown in the figure, use the translation line segment to translate the stairs vertically and horizontally upward to the left to form a rectangle with length and width of 6 meters and 4 meters respectively. The length of carpet is 6 + 4 = 10 meters, and the area of carpet is 10 × 2 = 20 square meters. It costs at least 20 × 40 = 800 yuan to buy carpet
How many meters does the carpet need at least when the slope angle is 30 degrees
The sum of all the heights of the steps of the stairs is that the slope is the hypotenuse, the height of the steps is the right angle side, the height of the right angle triangle, and the sum of all the lengths or widths of the steps is the hypotenuse of the slope side, the height of the steps is the straight edge, and a right angle side of the right angle triangle
The horizontal length of a staircase is 5 meters and the vertical height is 4 meters. If carpet is laid on the staircase, how many meters is it at least?
At least 5 + 4 = 9 meters
As shown in the figure: in the height of 1.5 meters, 5 meters wide stair surface carpet, carpet length at least how many meters?
As shown in the figure, after translation, it becomes a rectangle: the length of the carpet is the sum of the length and width of the rectangle; 5 + 1.5 = 6.5 (meters), a: the length of the carpet is at least 6.5 meters
