A company makes concrete bricks that are shaped like rectangular prisms. Each brick is 5 inches long, 4 inches wide, and 2 inche
1 answer:
Answer:
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:
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:
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.
The company would need of concrete to make 1600 bricks.

Answer:
$900
Step-by-step explanation:
Wages paid = $20 per hour
Transport allowance paid = $20 per day
Number of hours worked each day = 8 hours
Number of days worked each week = 5 days
To find:
Total amount paid in one week = ?
Solution:
First of all, let us find the total number of hours worked in one week.
8 hours a day and 5 number of days.
Therefore, total number of hours worked in one week = 8 5 = 40 hours
Total wages paid as per 40 hours = 40 20 = $800
Now, for these 5 days, transport allowances are paid $20 for each day.
Therefore total transport allowance = $20 5 = $100
Total wages paid = Wages as per 40 hours + Transport allowance = $800 + $100 = <em>$900</em>
