An open box is made from a square piece of sheet metal 19 inches on a side by cutting identical squares from the corners and turning up the sides. Express the volume of the box, V, as a function of the length of the side of the square cut from each corner, x.
A. V(x) = 361x
B. V(x) = (19  2x)2
C. V(x) = x(19  2x)
D. V(x) = x(19  2x)2

new length and width = 192x
area of base = (192x)^2
height = x
so
V = x (192x)^2 👍
