6*8=48 кв м площадь помещения
48/1,2=40 досок потребуется

Answer 2

Calculating the Number of Boards Needed to Cover the Floor

To calculate the number of boards needed to cover the floor, we can start by finding the total area of the floor and then divide it by the area of a single board.

The total area of the floor can be calculated using the formula: Total Area = Length × Width

Given: - Length of the room = 8 m - Width of the room = 6 m - Length of each board = 6 m - Width of each board = 20 cm

First, we need to convert the width of the boards to meters: 20 cm = 0.20 m

Now, we can calculate the total area of the floor: Total Area = 8 m × 6 m = 48 m²

Next, we calculate the area of a single board: Area of a Single Board = Length of Board × Width of Board Area of a Single Board = 6 m × 0.20 m = 1.2 m²

Finally, we can find the number of boards needed: Number of Boards = Total Area / Area of a Single Board Number of Boards = 48 m² / 1.2 m² = 40 boards

So, 40 boards of length 6 m and width 20 cm are needed to cover the floor.
