Arectangular box is twice as long as it is wide. the height of the box is 3 feet less than the width. if the box is x feet wide, what polynomial represents its volume in cubic feet?
a)4x-3
b)2x^3+6^2
c)2x^2-6x
d)2x^3-6x^2

In order to get the volume of a rectangular box, the formula would be V = LxWxH.
So given that Length L = 2w
H = 3-w
W = x
Let x be the width, so it will look like this.
V = (2x)(x-3)(x)
Multiply these and we will get 2x^3-6x^2.
Therefore, the answer would be option D. Hope this answer helps. Let me know if you need more help next time.
