If the cost of a .75 x 6.0 x 19.0 sheet of ABS plastic is $18.00, what is the cost to make 20 parts?
we do not know how much plastic each part takes
Damon the mass is .437 per part. It should be a simple problem for me but I am not sure right now. Thanks for your help.
ABS density varies from 1.0 to 1.4 grams/cc
you did not give any units except dollars
.437 what? grams, pounds, kg , oz ?
.437 lbs
To find the cost to make 20 parts out of a .75 x 6.0 x 19.0 sheet of ABS plastic, we need to determine the cost per part.
First, let's calculate the area of the sheet of ABS plastic:
Area = Length x Width
Area = 6.0 in x 19.0 in
Area = 114 square inches
Now, let's calculate the cost per square inch:
Cost per square inch = Cost of the sheet / Area of the sheet
Cost per square inch = $18.00 / 114 square inches
Cost per square inch ≈ $0.1579 (rounded to four decimal places)
Next, let's calculate the total area needed to make 20 parts.
Area per part = Area of the sheet / Number of parts
Area per part = 114 square inches / 20
Area per part = 5.7 square inches
Finally, let's calculate the cost to make 20 parts:
Cost per part = Cost per square inch x Area per part
Cost per part ≈ $0.1579 x 5.7 square inches
Cost per part ≈ $0.899 (rounded to three decimal places)
Therefore, the cost to make 20 parts out of a .75 x 6.0 x 19.0 sheet of ABS plastic is approximately $0.899.
