Hello,

I was stuck on this one Optimization problem for Calculus A.

The question is: A water tank is in the form of a triangular prism. The bottom is an equilateral triangle and the top is open. The volume of the tank must be 1000sqrt3 cubic inches. What is the minimum surface area of the tank? [Note: The Area of an equilateral triangle with a side length of x, is x²sqrt3/4]

Thanks
