Answer 1

Ответ:40 досок.
решение 1) 6*6равно36(кв. м)
2) 3 дм равен 30см равно0,3 м
3 ) 3*0,3рав0,9 кв м.
4) 36/0,9рав 40

Answer 2

20.потому что 3*2=6,а в 1м=10 дм 6м=60 дм 60:3=20

Answer 3

Calculating the Number of Boards Needed to Cover a Square Room

To calculate the number of boards needed to cover the floor of a square room with a side length of 6 meters, we can use the following approach:

1. Calculate the Area of the Room: - The area of a square is calculated by squaring the length of one of its sides. Therefore, the area of the room is 6 meters * 6 meters = 36 square meters.

2. Calculate the Area of Each Board: - The area of each board is calculated by multiplying its length by its width. Given that each board is 3 meters long and 3 decimeters (or 0.3 meters) wide, the area of each board is 3 meters * 0.3 meters = 0.9 square meters.

3. Determine the Number of Boards Needed: - To find the number of boards needed, we divide the total area of the room by the area of each board. Therefore, 36 square meters / 0.9 square meters = 40 boards.

Therefore, to cover the floor of a square room with a side length of 6 meters, you would need 40 boards.
