A rectangular box is to have a square base and a volume of 40 1'9. The material for the base costs 28 centsfftz, the material for the top costs 19 oentsfftz, and the material for the sides costs 12 oentsjftz. Ifx denotes the length of one side of the base (in feet), nd a function in the variablexgiving the total cost of materials used in constructing the box in cents. Total Cost, as a function ofx = Determine the domain of the total cost function. Enter your answer using interval notation. Domain of total oost function =
