A rectangular box with no top must have a volume of 2,500 cm³.

Three different materials will be used in the construction of this box. The bottom will be made out of material that costs 5 cents/cm², the front and back will be made out of material that costs 4 cents/cm², and material for the two sides costs 2 cents/cm².

What are the dimensions of the box (with volume 2,500 cm³) that will minimize the total cost of the materials?

10 * 12.5 * 20

at cost of 3000 cents
