Answer:
Step-by-step explanation:
Given
Required
The dimension that minimizes the cost
The volume is:
This gives:
Substitute
Make H the subject
The surface area is:
Area = Area of Bottom + Area of Sides
So, we have:
The cost is:
Substitute: and
To minimize the cost, we differentiate
Then set to 0
Rewrite as:
Divide both sides by W
Rewrite as:
Solve for
Take cube roots
Recall that:
Hence, the dimension that minimizes the cost is:
