Question
A company makes concrete bricks shaped like rectangular prisms. Each brick is 15 inches long, 10 inches wide, and 5 inches tall. If they used 15,000in3 of concrete, how many bricks did they make?bricks
Solution
To find out how many bricks the company made, we first need to calculate the volume of a single brick.
The volume of a rectangular prism (or a brick in this case) can be calculated using the formula: Volume = length * width * height
Given that each brick is 15 inches long, 10 inches wide, and 5 inches tall, we can substitute these values into the formula:
Volume = 15 inches * 10 inches * 5 inches = 750 cubic inches
So, each brick has a volume of 750 cubic inches.
The company used 15,000 cubic inches of concrete. To find out how many bricks they made, we divide the total volume of concrete used by the volume of a single brick:
Number of bricks = Total volume / Volume of a single brick Number of bricks = 15,000 cubic inches / 750 cubic inches = 20 bricks
So, the company made 20 bricks.
