a company makes concrete bricks shaped like rectangular prisms. Each brick is 10 inches long, 6 inches wide, and 4inches tall. If they used 13,200 cubic inches of concrete, how many bricks did they make?

55

Step-by-step explanation:

Volume of a rectangular prism is width time length times height.

V = WLH

The volume of each brick is:

V = (6 in) (10 in) (4 in)

V = 240 in³

The total volume is 13,200 in³, so the number of bricks is:

13,200 in³ / 240 in³ = 55
