Question

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.

Answer 1

So you are basically looking for the volume?

Answer 2

so is it like this V(x) = x(19-2x)^2

Answer 3

Well the volume would be 15*15*15 = 3375 I suppose you already got that far?

Answer 4

oh wait 19 in

Answer 5

my bad

Answer 6

It would be 19*19*19 = 6859

Answer 7

my choices are just functions not answers
A. V(x) = 361x
B. V(x) = (19-2x)^2
C. V(x) = x(19-2x)
D. V(x) = x(19-2x)^2

Answer 8

V = (19-2x)^2*x

Answer 9

that is what I got but it don't match my choices would it be D
