You decide to build a box with a square base

Last updated: 7/28/2022

You decide to build a box with a square base and with a height equal to half the length of a bottom side. The material you choose for the top of the box costs $6 per square foot. Since everyone will see the top of the box, that material is more expensive than what you choose for the sides of the box and the base: $4 per square foot. What equation expresses the cost of your box in terms of the height of the box? Be sure to show a labeled picture of the box.
