Question

Отец решил облицевать катили стен на кухне длина которой равна 4 м 50 см высота 3 м хватит ли ему 20 ящиков кафель если одна плитка имеет форму квадрата со страной 15 м в одном ящике находится 30 плиток

Answer 1

Сперва узнаем площадь кухни
4.5×3=13.5м
площадь 1 плитки 0.15×0.15=0.0225м
площадь 1 плитки умножается на количество плиток
0.0225×30=0.675 м
0.675 × 20 =13.5м
ответ: хватит плиток так как площадь кухни и площадь плиток равна.

Answer 2

Calculating the Number of Tiles Needed for the Kitchen Wall

To calculate whether 20 boxes of tiles will be sufficient to cover the kitchen wall, we need to determine the total area of the wall and then calculate the number of tiles required to cover that area.

- The length of the kitchen wall is 4 meters 50 centimeters. - The height of the kitchen wall is 3 meters. - Each tile is in the shape of a square with a side length of 15 centimeters. - There are 30 tiles in each box.

First, let's convert the length and height of the wall to the same unit for consistency.

Converting Length and Height to the Same Unit

The length of the wall is 4 meters 50 centimeters, and the height is 3 meters. To calculate the area, we need to convert the length to meters.

Length of the Wall: - 4 meters 50 centimeters = 4.50 meters Height of the Wall: - 3 meters

Now, we can calculate the total area of the wall.

Calculating the Total Area of the Wall

To find the total area of the wall, we will multiply the length and height of the wall.

Total Area of the Wall: - Total Area = Length × Height - Total Area = 4.50 meters × 3 meters - Total Area = 13.50 square meters

Calculating the Number of Tiles Required

Now that we know the total area of the wall, we can calculate the number of tiles needed to cover it.

Area of One Tile: - Area of One Tile = Side Length × Side Length - Area of One Tile = 0.15 meters × 0.15 meters - Area of One Tile = 0.0225 square meters

Number of Tiles Required: - Number of Tiles = Total Area / Area of One Tile - Number of Tiles = 13.50 square meters / 0.0225 square meters - Number of Tiles = 600 tiles

Conclusion

Based on the calculations, to cover the kitchen wall with a length of 4 meters 50 centimeters and a height of 3 meters, 20 boxes of tiles, with each box containing 30 tiles, will not be sufficient. A total of 600 tiles are required to cover the entire wall.
