Question

Підлога в кімнаті має форму прямокутника, розміри якого 4,6 м і 3,5 м. Для фарбування 1 м2 підлоги необхідно 250 г фарби, а 1 кг фарби коштує 24 грн. Скільки грошей витратять на фарбу, щоб пофарбувати підлогу в кімнаті? Поясни розв'язок.

Answer 1

Ответ:

96,6 грн

Пошаговое объяснение:

250г = 0,25 кг

1) 4,6 * 3,5 = 16,1 (м²) - площадь пола

2) 16,1 * 0,25 = 4,025 (кг) - требуется краски

3) 4,025 * 24 = 96,6 (грн) - потратят на краску

96,6грн = 96 гривен 60 копеек

Answer 2

To calculate the amount of money required to paint the floor in the room, we need to determine the total area of the floor and then calculate the amount of paint needed.

Calculating the Area of the Floor

The floor has the shape of a rectangle with dimensions of 4.6 m and 3.5 m. To find the area of the floor, we multiply the length by the width:

Area of the floor = length × width

Area of the floor = 4.6 m × 3.5 m

Area of the floor = 16.1 m² [[1]]

Calculating the Amount of Paint Needed

Given that 1 m² of floor requires 250 g of paint, we can calculate the total amount of paint needed by multiplying the area of the floor by the amount of paint required per square meter:

Total amount of paint needed = area of the floor × amount of paint required per square meter

Total amount of paint needed = 16.1 m² × 250 g/m²

Total amount of paint needed = 4025 g

Since 1 kg of paint costs 24 UAH, we can calculate the total cost of the paint by dividing the total amount of paint needed by 1000 (to convert grams to kilograms) and then multiplying by the cost per kilogram:

Total cost of paint = (total amount of paint needed / 1000) × cost per kilogram

Total cost of paint = (4025 g / 1000) × 24 UAH/kg

Total cost of paint = 96.6 UAH

Therefore, it will cost 96.6 UAH to paint the floor in the room.
