Question

Необходимо покрасить стены складского помещения ( Длина - 12 м, ширина - 8 м, высота 4м ) краской , причем краску покупают с запасом в 6% от площади окрашиваемой поверхности. Ширина дверного проема 4м, а высота 2.5м. Определите количество краски ( в литрах ), которую следует купить для покраски стен помещения полностью, от пола до потолка, если известно, что на 1 м^(2) окрашиваемой поверхности расходуется 0,2 литра краски.

Answer 2

Calculation of Paint Quantity

To determine the amount of paint needed to paint the entire warehouse, including the walls, floor, and ceiling, we need to calculate the total surface area to be painted.

The warehouse dimensions are as follows: - Length: 12 m - Width: 8 m - Height: 4 m

The surface area of the walls can be calculated by multiplying the perimeter of the warehouse by its height. The perimeter is calculated by adding the lengths of all four sides.

The perimeter of the warehouse is: 2 * (Length + Width) = 2 * (12 m + 8 m) = 2 * 20 m = 40 m

The surface area of the walls is: Perimeter * Height = 40 m * 4 m = 160 m²

To calculate the amount of paint needed, we need to consider that 6% of the total surface area will be used as a reserve. Therefore, the actual surface area to be painted is 94% of the total surface area.

The actual surface area to be painted is: 0.94 * 160 m² = 150.4 m²

Given that the paint consumption rate is 0.2 liters per square meter, the total amount of paint needed is: 0.2 liters/m² * 150.4 m² = 30.08 liters

Therefore, approximately 30.08 liters of paint should be purchased to paint the entire warehouse, from the floor to the ceiling.

Please note that these calculations assume a uniform surface and do not account for any additional factors such as windows, doors, or other obstacles.
