A company makes concrete bricks shaped like rectangular prisms. Each brick is 10 inches long, 9 inches wide, and 4 inches tall. If they used 18,000in3 of concrete, how many bricks did they make?

Respuesta :

Answer: 50 brick

In this case, you are given the concrete volume and the brick length(10inch), width(9 inch) and height(4inch). To answer this question,  you need to know the brick volume. The calculation would be:
Brick volume= length x width x height= 10 x 9 x 4= 360 inch cubic.

Then to know how many bricks made, the calculation would be:
Brick made= concrete volume/ brick volume
Brick made= 18000inch cubic/ 360 inch cubic= 50 brick
