Question

Расход краски на покрытие составляет 180 г на 1м в квадрате .хватит ли 3кг краски чтобы покрасить стену длиной 6м и высотой 3 м

Answer 1

Решение:
1. Найдём площадь стены:
6м*3м=18м²
2. Вычислим необходимое количество краски:
18м²*180г=3240г=3 кг 240г
Отсюда следует, 3-х кг краски не хватит.

Answer 2

Calculating Paint Usage for Wall

To calculate the amount of paint needed to cover a wall, we can use the formula:

Amount of paint (in kg) = Area to be painted (in square meters) × Paint usage per square meter (in kg/m²)

Given: - Area to be painted = 6m (length) × 3m (height) = 18 square meters - Paint usage per square meter = 180g = 0.18kg

We can calculate the amount of paint needed using the formula:

Amount of paint = 18m² × 0.18kg/m² = 3.24kg

Conclusion

To paint a wall with a length of 6m and a height of 3m, you would need approximately 3.24kg of paint. Therefore, 3kg of paint would be sufficient to cover the wall.
