Solve the problem.From a 38-inch by 38-inch piece of metal, squares are cut out of the four corners so that the sides can then be folded up to make a box. Let x represent the length of the sides of the squares, in inches, that are cut out. Express the volume of the box as a function of x. Give the function and state its domain.
A. V = 4x3 - 152x2 + 1444x: 0 < x < 19
B. V = 2x3 - 114x2 + 38x: 0 < x < 19
C. V = 4x3 - 152x2 + 1444x: x < 38
D. V = 2x3 - 114x2 + 1444x: x >0
