Question

A company makes concrete bricks that are shaped like rectangular prisms. Each brick is 5 inches long, 4 inches wide, and 2 inches tall. How much concrete will they need to make 1600 bricks?

Answer 1

Answer:

$64000 \ in.^3$

Step-by-step explanation:

The amount of concrete needed would be measurable by the volume of the brick, since a brick is three-dimensional.

The volume of a rectangular prism is found using the formula: $V=l \times w \times h$

You are given the length (5 in.), width (4 in.), and height (2 in.) of the bricks. Find how much concrete is needed to make a single brick.

Single brick volume:

• $5 \ in. \ \times 4 \ in. \ \times 2 \ in.$
• $40 \ in.^3$

In order to find how much concrete would be needed to make 1600 bricks, you would need to multiply the amount of concrete needed to make 1 brick by 1600.

• $40\ in.^3 \times 1600$
• $64000 \ in.^3$

The company would need $64000 \ in.^3$ of concrete to make 1600 bricks.
