Question

Стену с измерениями 3.05 м и 2.02 м необходимо обклеить обоями. сколько рулонов обоев длиной 13 м и шириной 50 см для этого необходимо

Answer 1

Переводим длину и ширину стены в см: 305 и 202.                                          Находим площадь стены: 305*202=61610 см2.                                                  Переводим длину обоев в см: 13000.                                                                 Находим площадь обоев: 13000*50=65000 см2
Находим количество рулонов:   61610/65000=0,95

Answer 2

Calculating Wallpaper Rolls Needed

To calculate the number of wallpaper rolls needed to cover a wall with dimensions of 3.05 m by 2.02 m, we can follow these steps:

1. Calculate the Total Area of the Wall: - The total area of the wall can be calculated by multiplying the height by the width. - Total area = height * width - Total area = 3.05 m * 2.02 m - Total area = 6.161 m²

2. Determine the Coverage of Each Wallpaper Roll: - The coverage of each wallpaper roll is given by its length and width. - Given: Length of wallpaper roll = 13 m, Width of wallpaper roll = 50 cm = 0.5 m - Coverage of each wallpaper roll = Length * Width - Coverage of each wallpaper roll = 13 m * 0.5 m - Coverage of each wallpaper roll = 6.5 m²

3. Calculate the Number of Rolls Needed: - Number of rolls = Total area / Coverage of each roll - Number of rolls = 6.161 m² / 6.5 m² - Number of rolls ≈ 0.946

Conclusion

To cover a wall with dimensions of 3.05 m by 2.02 m using wallpaper rolls that are 13 m in length and 50 cm in width, approximately 0.946 rolls would be needed. Since it's not possible to use a fraction of a roll, it would be advisable to round up to the nearest whole number, so at least 1 roll would be needed to cover the wall.
