The height of a box that bill is shipping is 4 inches less than the width of the box. the length is 10 inches more than twice the width. the volume of the box is 264 cubic inches. what are the dimensions of the box?

This is the concept of algebra, let the width be x
height=x-4
length=2x+10
the volume of the box is:
volume=length*width*height
=x(x-4)(2x+10)
expanding the above we get:
(x^2-4x)(2x+10)
=x^2(2x+10)-4x(2x+10)
=2x^3+2x^2-40x=264
solving the above we get real solution will be
x=6
thus we conclude that the width is x=6 inches
length=2*6+10=22 inches
height=x-4=6-4=2 inches
thus the dimension will be:
width=6 inches, length=22 inches, height=2 inches

I'm pretty sure it's b). i try drawing the functions out and b is the one that stands out or isnt a "line"

Ithink it would be 1.24 pounds
