A room is 12 m by 10 m. Find the cost of covering its floor with break...
Divide:
1000÷220=0.22
so, 0.22×10=0.220
and, 0 is not value with another point numbers
so, 220×10=₹2200

A room is 12 m by 10 m. Find the cost of covering its floor with break...
Calculating the Number of Bricks
To calculate the cost of covering the floor of the room with bricks, we first need to determine the number of bricks required.
Given that the room is 12 m by 10 m, we need to convert these measurements into centimeters to match the dimensions of the bricks.
Conversion of Dimensions
- Length of the room: 12 m = 1200 cm
- Width of the room: 10 m = 1000 cm
Calculating the Area of the Room
To find the total area of the room, we multiply the length and width of the room.
- Area of the room = Length × Width = 1200 cm × 1000 cm = 1,200,000 cm²
Calculating the Area of One Brick
The area of one brick is calculated by multiplying the length and width of the brick.
- Area of one brick = Length × Width = 20 cm × 6 cm = 120 cm²
Calculating the Number of Bricks Required
To find the number of bricks required to cover the entire floor, we divide the total area of the room by the area of one brick.
- Number of bricks required = Area of the room ÷ Area of one brick = 1,200,000 cm² ÷ 120 cm² = 10,000 bricks
Calculating the Cost of the Bricks
Given that the cost of one thousand bricks is र 220, we can calculate the cost of 10,000 bricks.
- Cost of 10,000 bricks = र 220 × (10,000 ÷ 1,000) = र 220 × 10 = र 2200
Therefore, the cost of covering the floor of the room with bricks is र 2200.
