A storage box with a square base must have a volume of 80 cubic centimeters. The top and bottom cost $\$ 0.20$ per square centimeter and the sides cost $\$ 0.10$ per square centimeter. Find the dimensions that will minimize cost.
Added by Chad S.
Step 1
We are given that the volume of the box is 80 cubic centimeters, so we have \( x^2 \times y = 80 \). Show more…

A storage box with a square base must have a volume of 90 cubic centimeters. The top and bottom cost $0.40 per square centimeter and the sides cost $0.20 per square centimeter. Find the dimensions that will minimize cost. (Let x represent the length of the sides of the square base and let y represent the height. Round your answers to two decimal places.)
