A company makes concrete bricks shaped like rectangular prisms. Each brick is 11 inches long,8 inches wide, and 5 inches tall. If they 11,000 in^3 used of concrete, how many bricks did they make?
Answers
The number of bricks that they make will be 25 bricks.
What is the volume of the rectangular prism?
Let the prism with a length of L, a width of W, anda height of H. Then the volume of the prism is given as
V = L x W x H
A company makes concrete bricks shaped like rectangular prisms. Each brick is 11 inches long, 8 inches wide, and 5 inches tall. Then the volume of each brick will be
V = 11 x 8 x 5
V = 440 cubic inches
If they have used 11,000 cubic inches of concrete, then the number of bricks that they make will be
⇒ 11,000 / 440
⇒ 25 bricks
The number of bricks that they make will be 25 bricks.

5*8*11=440
To find how many bricks they made divide 11,000 by 440 which is 25
They made 25 bricks

Answer:
y = 4x + 7
Step-by-step explanation:
parallel = same slope
y = 4x + b
plug in (-4, -9)
-9 = 4(-4) + b
-9 = -16 + b
b = 7
y = 4x + 7
Answer:
7=4x+7
Step-by-step explanation:
To do this you would just plug in (-4,-9) into the equation y=mx+b so we would get -9=4(-4)+b when you simplify you will get -9=-16+b so we would add 16 to both sides and we would get 7=b so we would know that the y intercept is 7 and we know that if a line is parallel to another line is just has a different b so for our equation we would get 7=4x+7

Final answer:
Given the dimensions of the brick, we first calculated its volume in cubic meters. Then we calculated the volume of the wall in cubic meters. Dividing the volume of the wall by the volume of a single brick, we find that we need 20,000 bricks to build the wall.
Explanation:
This is a problem in Mathematics, specifically involving volume and unit conversion. The volume of the brick can be calculated using the formula for the volume of a rectangular prism, Volume = length x width x height. The dimensions given for the brick are in centimeters and the wall dimensions are given in meters. Therefore, we must convert the brick dimensions to meters: 30 cm = 0.3 m, 10 cm = 0.1 m and 7.5 cm = 0.075 m. The volume of one brick is 0.3 m * 0.1 m * 0.075 m = 0.00225 cubic meters.
The volume of the wall is also given by the formula length x width x height, so it is 30 m * 2 m * 0.75 m = 45 cubic meters. To find the number of bricks required to fill this volume, divide the volume of the wall by the volume of a single brick, 45 m³ / 0.00225 m³ = 20000 bricks. Thus, it will take 20,000 bricks to build the wall.
