Question
A company makes concrete bricks that are shaped like rectangular prisms. Each brick is 8 inches long, 5 inches wide, and 2 inches tall. How much concrete will they need to make 1600 bricks?
Solution
To find out how much concrete the company will need, we first need to find the volume of one brick. The volume of a rectangular prism (or a brick in this case) can be found using the formula: length x width x height.
Step 1: Calculate the volume of one brick The dimensions of the brick are given as 8 inches long, 5 inches wide, and 2 inches tall. So, the volume of one brick is 8 * 5 * 2 = 80 cubic inches.
Step 2: Calculate the total volume of concrete needed The company wants to make 1600 bricks. So, the total volume of concrete needed is 1600 * 80 = 128,000 cubic inches.
So, the company will need 128,000 cubic inches of concrete to make 1600 bricks.
