Step 1
The surface area of a rectangular box can be calculated by finding the area of each face and adding them together. The box has 6 faces: 2 sides, 2 ends, a top, and a bottom. The area of each side face is height multiplied by width, which is 10cm * 40cm = Show more…

A small box with an open top is to be constructed such that the length of the base is four times its width. The volume of the box will be 160 cubic centimeters. Construction of the base will cost $10 per cm² while the four sides will cost $8 per cm². Find the dimensions of the box (length, width, and height) that will minimize the cost of its construction.

We're building another box! This box is to be constructed with a total volume of 2304 cm³, but the sides have different costs. The top, bottom, left and right sides cost $3 per cm², but the front and back cost $4 per cm². What are the dimensions of the box that have the correct volume, but minimize cost?
