Answer:
6.3 cm by 6.3 cm by 12.6cm
Step-by-step explanation:
Volume of the box=
The minimal dimensions of a box always occur when the base is a square.
Surface Area of a cylinder=
Surface Area of the sides and bottom=
Surface Area for the top =
The material for the sides and bottom costs $0.05 per
The material for the top costs $0.15 per
Therefore Cost of the box
Recall:
The minimum value of C is at the point where the derivative is zero.
The dimensions that would minimize the cost are 6.3 cm by 6.3 cm by 12.6cm
Move all the terms containing Ф to the left side ...
0 = 0
