Question

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?​

1 Answer

  • Answer:

    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
