Question 941954: A box with a square base and top has height h = 6 meters, as shown in the diagram below.
The square base will be made of reinforced material and costs $1.25 per square meter. Materials for the five remaining surfaces of the box cost $0.65 per square meter.
Let x be the measurement of the edge of the bottom of the box, in meters. Express the cost of the surface area of the box, including top and bottom, as a function of x. Don't include the dollar sign in your answer.

Bottom, 1.25x%5E2 cost.
Top, 0.65%2Ax%5E2 cost.
Four sides, 4%2Ahx%2A0.65 cost.

All the cost, 1.25x%5E2%2B0.65x%5E2%2B4%2A%280.65%29%2Ahx
