Question

Организация закупила для покраски пола в коридоре 4 банки краски по 2 кг в каждой. Длина коридора 16 м, что на 140 дм больше его ширины. Хватит ли краски, если на 1 м² идёт 250 г? Ответ обоснуйте

Answer 1

1)4*2=8(кг) 8000(гр) краски всего
2) 160-140=20 (дм) ширина
3) 16*2=32(м^2) площадь коридора
4) 250*32=8000(г) 8(кг) краски понадобиться

Answer 2

Calculation of Paint Required

To determine if the organization has enough paint to cover the floor in the corridor, we need to calculate the area of the floor and compare it to the amount of paint available.

Given information: - The corridor is 16 meters long. - The length of the corridor is 140 decimeters (dm) longer than its width. - Each can of paint contains 2 kg.

To calculate the area of the floor, we need to find the width of the corridor. Let's denote the width as x.

According to the given information, the length of the corridor is 140 dm longer than its width. Since 1 meter is equal to 10 decimeters, we can write the equation:

Length = Width + 140 dm

Converting the length from meters to decimeters:

16 m = 160 dm

Substituting the values:

160 dm = x + 140 dm

Simplifying the equation:

x = 160 dm - 140 dm x = 20 dm

Therefore, the width of the corridor is 20 decimeters.

To calculate the area of the floor, we multiply the length and width:

Area = Length * Width Area = 16 m * 20 dm Area = 320 dm²

Given that 1 m² requires 250 g of paint, we need to convert the area from decimeters squared to meters squared:

1 m² = 100 dm²

Converting the area:

320 dm² = 3.2 m²

Now, we can calculate the amount of paint required:

Amount of paint required = Area * Paint consumption per m² Amount of paint required = 3.2 m² * 250 g/m² Amount of paint required = 800 g

Since each can of paint contains 2 kg (2000 g), we can determine if there is enough paint:

Conclusion: The organization has enough paint to cover the floor in the corridor. The amount of paint required is 800 g, and each can contains 2000 g of paint. Therefore, there is sufficient paint available.
