Solve the problem.A rectangular box with volume 345 cubic feet is built with a square base and top. The cost is $1.50 per square foot for the top and the bottom and $2.00 per square foot for the sides. Let x represent the length of a side of the base. Express the cost of the box as a function of x. Give the function and state its domain.
A. C(x) = 3x2 + 
Domain: {x| x > 0}
B. C(x) = 4x + 
Domain: {x| x > 0}
C. C(x) = 3x2 + 
Domain: {x| x > 4}
D. C(x) = 2x2 + 
Domain: {x| x < 10}
