Question

Расход эмалевой краски на однослойное покрытие составляет 180г на 1 квадратный метр.Хватит ли 3 кг эмали,чтобы покрасить стену длиной 6 м и высотой 3м?

Answer 1

Площадь стены: 6*3=18 кв.м.

Расход краски: 18*180=3240 г = 3,24 кг.

Ответ: не хватит

Answer 2

Calculation of Paint Consumption

To determine if 3 kg of enamel paint is sufficient to paint a wall with dimensions 6 meters in length and 3 meters in height, we need to calculate the total area of the wall and then determine the paint consumption based on the given rate.

The formula to calculate the area of a rectangular wall is:

Area = Length × Height

Using the given dimensions, we can calculate the area of the wall:

Area = 6 meters × 3 meters = 18 square meters

According to the information provided, the enamel paint consumption for a single coat is 180 grams per square meter. Therefore, we can calculate the total paint consumption for the wall:

Paint Consumption = Area × Paint Consumption Rate

Paint Consumption = 18 square meters × 180 grams per square meter

Now, let's calculate the paint consumption:

Paint Consumption = 3,240 grams

Therefore, 3 kg (or 3,000 grams) of enamel paint will be sufficient to paint the wall, as the calculated paint consumption is 3,240 grams.
