A road 100m long and 20m wide to be paved with bricks. Each measuring by 25cm by 10cm. Find the no. Of bricks?
since the brick dimensions divide the road dimensions evenly, it does not matter which way the bricks are laid (assuming that the brick's edges are parallel with the road's).
So, we can just divide the area of the road by the area of a brick:
(100m * 20m)/(.25m * .10m) = 80,000 bricks
To find the number of bricks needed to pave the road, we need to calculate the area of the road and then divide it by the area of each brick.
1. Calculate the area of the road:
Area = Length × Width
Area = 100m × 20m
Area = 2000 square meters
2. Convert the area to square centimeters:
1 square meter = 10000 square centimeters
Area = 2000 × 10000 square centimeters
Area = 20,000,000 square centimeters
3. Calculate the area of each brick:
Area of brick = Length × Width
Area of brick = 25cm × 10cm
Area of the brick = 250 square centimeters
4. Divide the area of the road by the area of each brick to find the number of bricks:
Number of bricks = Area of road / Area of brick
Number of bricks = 20,000,000 / 250
Number of bricks = 80,000
So, you will need 80,000 bricks to pave the road.
To find the number of bricks needed to pave the road, we need to calculate the area of the road and divide it by the area of one brick.
First, let's convert the measurements to meters.
Length of the brick = 25 cm = 0.25 m
Width of the brick = 10 cm = 0.10 m
Now, let's calculate the area of the road:
Area of the road = Length x Width = 100m x 20m = 2000 sq.m
Next, let's calculate the area of one brick:
Area of one brick = Length x Width = 0.25m x 0.10m = 0.025 sq.m
Finally, we can determine the number of bricks needed:
Number of bricks = Area of the road / Area of one brick
Number of bricks = 2000 sq.m / 0.025 sq.m = 80,000 bricks
Therefore, you will need 80,000 bricks to pave the road.
