Question

Необходимо покрыть кафельной плиткой пол ,имеющий форму прямоугольника со сторонами 4 м 50 см и 2 м 40 см .Плитки имеют форму квадрата со стороной 15 см .Сколько ящиков потребуется,если в каждом ящике 50 плиток? решите плизззззз дам 100 баллов и + сделаю лучшим ответом

Answer 1

1 м = 100 см

4 м 50 см = 450 см

2 м 40 см = 240 см

450 : 15 = 30 плиток в длину в один ряд

240 : 15 = 16 рядов получим в ширину

330 * 16 = 480 плиток нужно всего

480 : 50 = 9 ц. 3\5 ящиков

Ответ: 9 целых 3\5 ящиков.

Answer 2

Calculation of the Number of Tile Boxes Needed

To calculate the number of tile boxes needed to cover the rectangular floor, we need to determine the area of the floor and the area of each tile.

The floor has dimensions of 4 meters 50 centimeters by 2 meters 40 centimeters. To simplify the calculation, we can convert these dimensions to centimeters:

- Length of the floor: 4 meters 50 centimeters = 450 centimeters - Width of the floor: 2 meters 40 centimeters = 240 centimeters

The area of the floor can be calculated by multiplying the length and width:

Area of the floor = Length × Width = 450 cm × 240 cm = 108,000 square centimeters.

The tiles are square-shaped with a side length of 15 centimeters. To calculate the area of each tile, we square the side length:

Area of each tile = Side length × Side length = 15 cm × 15 cm = 225 square centimeters.

To find the number of tile boxes needed, we divide the area of the floor by the area of each tile and then divide by the number of tiles in each box. Each box contains 50 tiles.

Number of tile boxes needed = (Area of the floor ÷ Area of each tile) ÷ Number of tiles in each box = (108,000 cm² ÷ 225 cm²) ÷ 50 = 240 boxes.

Therefore, you will need 240 tile boxes to cover the floor.

Please note that the calculations provided are based on the given dimensions and assumptions. It is always a good idea to purchase some extra tiles to account for any breakage or future repairs.
