A path is 3 feet wide and is paved Weight square brakes that are 3 inches wide. How many bricks wide is the path
konstantin123 [22]
The area of the path is can be solved using the equation below:
Area path = wide²
First, let us convert 3 feet to inches such as shown below:
3 feet * (12 inches / 1 foot) = 36 inches
Area of the path = 36²
Area of the path = 1296 inches²

Solving for the area of the square bricks
Area of the bricks = (3 inches)²
Area of the brick = 9 inches²

Solving for the number of bricks, we have it:
Total number of bricks = Area of the path/area of the bricks
Total number of bricks = 1296 / 9
Total number of bricks = 144 pieces

The answer is 144 total number of bricks.
